Abstract

Performed are an accommodation step of accommodating a pair of conductive members in a die, a sealing step of injecting a resin to seal the conductive members, and an extraction step of extracting a conductive member module. In the sealing step, the conductive members are sealed while a force is applied by the resin injected into the die to the individual conductive members in directions away from each other, and the individual conductive members are supported by support members disposed outside.
