  "abstract": "As an electronic component conveyance device in which an electronic component is unlikely to jam in a conveyance path. A first magnetic force generation unit is provided lateral to a first sidewall in a midstream part. A second magnetic force generation unit is provided downstream of the first magnetic force generation unit and lateral to a second sidewall in the midstream part. The midstream part includes a first transition part connected with an upstream part and a second transition part connected with a downstream part. The first sidewall is parallel to a conveyance direction in the first transition part. The second sidewall extends in a direction different from the conveyance direction in the first transition part. The second sidewall is parallel to the conveyance direction in the second transition part. The first sidewall extends in a direction different from the conveyance direction in the second transition part.",
