A power converter includes a power semiconductor module, a first flow path forming body and a second flow path forming body that forms a housing space for storing the power semiconductor module and the first flow path forming body, in which the first flow path forming body is configured of a first side wall section, a second side wall section, and a bottom surface section, the first side wall section forms a first flow path space between one surface of the power semiconductor module and the first side wall section, the second side wall section forms a second flow path space between the other surface of the power semiconductor module and the second side wall section, and cooling refrigerant flows through the housing space, the first flow path space, and the second flow path space.
