There is provided an electric-power conversion apparatus that can suppress bending of a substrate at a time when vibration occurs in the substrate.The electric-power conversion apparatus includesa semiconductor module having a main body portion held to a case and two or more control terminals pulled out from the main body portion,a substrate on which respective connection portions to which the two or more control terminals are fixed in substantially linear alignment are arranged in such a way as to be substantially parallel to the alignment direction and in such a way as to face each other, anda transformer that is mounted at a position, on the substrate, avoiding a virtual center line, the respective distances from which to the facing connection portions are equal to each other, and whose gravity center is apart from a first mounting surface of the substrate in the normal direction.
