Abstract
The present invention aims to suppress a coolant from bypassing a non-cooling unit without lowering the productivity. The power converter according to the present invention includes: a power semiconductor module; and a flow path forming body having a flow path in which the power semiconductor module is disposed and an opening which is connected with the flow path, wherein the power semiconductor module includes a first fin formed on one surface and a second fin formed on another surface which faces the one surface so as to sandwich the semiconductor element, the flow path forming body has a first coolant control unit and a second coolant control unit which are arranged so as to sandwich the first fin, the first coolant control unit and the second coolant control unit are formed to be overlapped with a region of the power semiconductor module where the first fin is not formed, and a first flow path is formed along the first coolant control unit and the second coolant control unit.
