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.
