A motor-driven compressor includes a housing having a compression portion for compressing refrigerant, a motor for driving the compression portion, and a drive circuit for controlling the motor. A connection member having a plate shape is disposed at one end of the motor. The connection member connects a plurality of coils of the motor to the drive circuit. In such motor-driven compressors, because the rolling and bundling of electrical wires extending from coils to connect the drive circuit are not necessary, the size of the motor-driven compressor may be reduced.
