PROBLEM TO BE SOLVED: To provide a motor unit that downsizes a substrate.SOLUTION: In a motor unit 1, a motor 20 and an inverter are housed integrally. The motor unit 1 includes: a first case that houses a rotor 21, and a stator 22, of the motor 20; a second case that surrounds and covers an end of a rotating shaft of the motor 20; a first fastening section that fastens the first and second cases together; and a substrate that has mounted thereon a drive circuit for driving switching elements of the inverter. The substrate is sandwiched between the first and second cases under stress produced by the first and second cases being fastened by the first fastening section. |
