Abstract: An electric power converter includes a semiconductor module, an electronic component, a plurality of cooling tubes, a case, a main pressure member for pressing a stacked semiconductor section in a stacking direction, and a sub-pressure member for pressing a stacked component section in the stacking direction. The stacked semiconductor section and the stacked component section are stacked in line. A pressing force of the main pressure member is greater than a pressure pressing force of the sub-pressure member. The main pressure member is disposed at an end portion of the stacked component section far from the stacked semiconductor section. A supporting portion that supports the stacked semiconductor section from the stacked component section side is disposed in the case so as to prevent the pressing force of the main pressure member from acting on the stacked component section.

Abstract: A conductive member module has a pair of conductive members formed in a plate shape and facing each other, and a sealing part for sealing the pair of conductive members. The conductive member module is produced by performing an accommodation step, a sealing step, and an extraction step. In the sealing step, the conductive members are sealed with a resin injected into a die while a force is applied by the resin to the individual conductive members in directions to approach each other in a facing orientation of the pair of conductive members.
