A compressor includes a valve base plate, which is arranged between a suction chamber and a compression chamber and has a suction port. The valve base plate includes a sealing surface, a recessed groove, a receiving surface, and a support surface. The sealing surface is flush with a fixing surface and contacts the valve portion in an annular manner. The recessed groove is located at an outer side of the sealing surface and recessed with respect to the fixing surface. The recessed groove includes a bottom portion and separates an edge portion of the valve portion from the bottom portion. The receiving surface is flush with the fixing surface and capable of contacting a distal zone of the valve portion. The support surface is flush with the fixing surface and capable of contacting a middle zone located at an inner side of the sealing surface of the valve portion.
