To provide an electric power converter which inhibits impairment of conductivity between a cover and a case.SOLUTION: An electric power converter includes: an electric component 650; a drive part 660; a case 730; a first connector 710 connected to the drive part; a cover 740 connected to the case by a connection bolt 747a; and a second connector 720 connected to the first connector. The case has screw holes 735 into which the connection bolts are inserted. The cover has a fastening part 742 including an outer surface 742a and a connection bolt hole 744a opening on a rear surface 742b. The second connector has a plate-like hood part 727, a part of the outer surface of the cover is covered with a non-conductive paint 746. A peripheral edge surface 745a around the connection bolt hole is exposed from the non-conductive paint. The connection bolt is inserted into the connection bolt hole and the screw hole. A seating surface of the connection bolt and the peripheral edge surface are brought into contact with each other. Further, the peripheral edge surface, which is exposed from the non-conductive paint and is not brought into contact with the seating surface of the connection bolt, is covered with the hood part.SELECTED DRAWING: Figure 4
