To provide an electronic part transfer carrier capable of preventing an electric trouble in an electronic part when the part is transferred and capable of increasing reliability in part transfer.

In an electronic part tray 10 so constituted that a plurality of housing cavities X which house the electronic part 100 are formed in a lattice pattern by a peripheral wall to be a barrier plate and the part 100 is housed inside the housing cavities X, a loading step section 14 where the edge section 103 of a substrate in the part 100 formed in a space inside the housing cavities is loaded and a contact housing space 17 which is connected with the section 14 and houses a group of contacts formed on the substrate of the part 100 are provided, the periphery of the space 17 is surrounded by an inclined wall 15, and a gradient bigger than a draft at the time of injection molding is arranged to a vertical plane relative to the wall 15.
