    "1. A laminated fabric for protective clothing comprising two or more fabric layers including an outer layer and an inner layer, with the inner layer disposed on a skin side, when used in protective clothing, wherein the outer layer is a fabric composed of a fiber having an LOI value (limiting oxygen index) of 21 or more measured by JIS L 1091 E method, the inner layer is a fabric composed of a fiber having an LOI value (limiting oxygen index) of 21 or more measured by JIS L 1091 E method, and a thermal diffusivity of 2.2×10 −6 m 2 ·s −1 or more, and the fabric has a porosity ranging from 85% to 98%, a thickness ranging from 0.5 mm to 8.0 mm and a basis weight ranging from 80 g/m 2 to 250 g/m 2. 2. The laminated fabric for protective clothing according to claim 1, wherein the fabric of the inner layer has an air permeability of 20 cm 3 /m 2 ·sec or more. 3. The laminated fabric for protective clothing according to claim 1, wherein the fiber composing the fabric of the inner layer is composed of a fiber-forming polymer and contains fine particles composed of a material having a thermal conductivity of 70 W/(m·k) or more. 4. The laminated fabric for protective clothing according to claim 3, wherein the fiber composing the fabric of the inner layer is composed of the fiber-forming polymer and contains at least one of fine particles of carbon powder, carbon nanotubes, diamond, silver, copper, gold and aluminum. 5. The laminated fabric for protective clothing according to claim 1, wherein the fabric of the inner layer is a nonwoven fabric. 6. The laminated fabric for protective clothing according to claim 1, wherein the fabric of the inner layer is raised. 7. The laminated fabric for protective clothing according to claim 1, wherein the fabric of the inner layer contains carbon fiber in an amount of 50% by weight or more. 8. The laminated fabric for protective clothing according to claim 1, wherein the fabric has an intermediate layer between the outer layer and the inner layer, and the intermediate layer is a fabric in which a moisture-permeable waterproof film is laminated on and fixed to a fabric composed of a fiber having an LOI value (limiting oxygen index) of 25 or more measured by JIS L 1091 E method. 9. The laminated fabric for protective clothing according to claim 1, wherein the fabric has a back fabric layer arranged on a further skin side than the inner layer, when used in protective clothing. 10. Protective clothing using the laminated fabric for protective clothing according to claim 1. 11. Protective clothing using the laminated fabric for protective clothing according to claim 2. 12. Protective clothing using the laminated fabric for protective clothing according to claim 3. 13. Protective clothing using the laminated fabric for protective clothing according to claim 4. 14. Protective clothing using the laminated fabric for protective clothing according to claim 5. 15. Protective clothing using the laminated fabric for protective clothing according to claim 6. 16. Protective clothing using the laminated fabric for protective clothing according to claim 7. 17. Protective clothing using the laminated fabric for protective clothing according to claim 8. 18. Protective clothing using the laminated fabric for protective clothing according to claim 9."
