A highly reliable electric power converter (200) with reduced parasitic inductance including a capacitor module (300) having a DC terminal, an inverter converting a direct current into an alternating current, and heat release fins (506,507) cooling the inverter (200). The inverter (200) has a power module (500) including a plurality of power semiconductor elements, a metallic base (944), a dielectric substrate (956) provided on one face of the metallic base, a power semiconductor element fixed to the dielectric substrate (956), and a DC terminal; the metallic base has heat release fins (506,507) on the other face; the DC terminals are each formed by stacking flat plate conductors via an insulator; the two positive and negative DC terminals have respective front ends bent in opposite directions; a plane including the bent sections is used for connecting the power module (500) and the capacitor module (300); and the insulators overlap each other at the connection surface. |
