A motor-driven compressor includes a compression unit having a compression chamber, a rotation shaft, an electric motor having a coil, a motor driving circuit, a housing, and a shaft support. The coil includes a first coil end, which is relatively close to the motor driving circuit, and a second coil end, which is relatively close to the compression unit. The housing includes a first area and a second area. A refrigerant passage communicates the first area with the second area. The shaft support includes a guide wall that guides the refrigerant to flow along the radial outer surface of the second coil end. The refrigerant guided by the guide wall is drawn into the compression chamber from the second area through a first suction passage. The first suction passage and the refrigerant passage are arranged at opposite sides of the rotation shaft. |
