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.
