Abstract: A sensor unit includes a bus bar and a magneto-electric conversion device. The bus bar connects a plurality of switch elements constituting a part of a power conversion circuit and a motor. The magneto-electric conversion device is disposed to face a middle portion of the bus bar across a clearance in a predetermined direction to detect a magnetic field caused by an electric current flowing through the bus bar, to thereby detects the electric current. The bus bar includes a first end and a second end. The first end of the bus bar is connected to one of a switch terminal extending from the switch elements and a motor terminal extending from the motor, and the second end of the bus bas is connected to the other of the switch terminal and the motor terminal.

Abstract: In a power converter, busbars are connected to respective power terminals. The power terminals include at least one narrow power terminal. The at least one narrow power terminal includes a first portion having a first thermal resistance and a first rigidity, and a second portion having a second thermal resistance and a second rigidity, the second thermal resistance being higher than the first thermal resistance, the second rigidity being smaller than the first rigidity.
