A compressor module, as a component of a refrigerant cycle device, is attached to a casing that houses a refrigeration cycle device. The compressor module includes a compressor that compresses refrigerant, a supporting member that supports the compressor, a vibration-reducing rubber body that is attached to the supporting member, ancillary equipment that is added to the compressor, a base supporting the supporting member via the vibration-reducing rubber body and supporting the ancillary equipment with a portion of the base other than the portion supporting the supporting member.
