The six lead wires u1n, v1n, w1n, u2n, v2n, w2n are connected to each other by an electroconductive pattern provided to the circuit board 21 and are configured as neutral points. The lead wires u1, v1, w1 and u2, v2, w2 are connected, via a wiring pattern on the circuit board, to output terminals of a drive circuit configured from an electronic component mounted on the circuit board 21 within the electrical unit 20.

According to the present embodiment, the precision of the leading-out direction of the lead wires led out to the exterior from the motor housing 2 can be increased; therefore, it is possible to keep an amount by which distal-end positions of the lead wires deviate from prescribed positions (positions suited for connecting to electrical-unit-side terminal sections) within a permissible range. Therefore, it is possible to enable automatic connection of the distal ends of the lead wires and the electrical-unit-side terminal sections using an automatic assembly machine, and it is also possible to enable an operation for assembling the device to be performed efficiently. The connection of the distal ends of the lead wires and the electrical-unit-side terminal sections is performed by soldering, welding (for example, TIG welding), etc.
