Claim Text:
1. A power converter comprising: a stack unit in which a plurality of semiconductor modules and a plurality of refrigerant paths through which refrigerant flows are stacked, the plurality of semiconductor modules having power terminals projecting from a body in which a semiconductor element is encapsulated; a set of busbars electrically connected to the power terminals, the set of busbars including: a frame portion surrounding the stacked unit from at least three directions when viewed from the projecting direction, the set of busbars being fixed to the frame portion; a terminal holder having a mount surface on which terminals of the AC busbars are mounted; and a current sensor that measures a current flowing through at least part of the AC busbars, wherein: the frame portion and the terminal holder are integrated to each other to constitute a resin-molded body; the AC busbars are separate members from the resin-molded body; the AC busbars are fixedly mounted on the resin-molded body; the current sensor is attached to a position of the terminal holder, the position being closer to the frame portion than to the mount surface; and at least part of the AC busbars is fitted in a through hole formed through the current sensor.
