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. An interval between the first sidewall and a second sidewall in the midstream part is larger than an interval between the first sidewall and the second sidewall in an upstream part and an interval between the first sidewall and the second sidewall in a downstream part. The first sidewall is flat across the upstream part, the midstream part, and the downstream part.
