• an inverter including a target electronic component group of a noise reduction element and a voltage smoothing element and driving the electric motor;
• a housing accommodating the compression mechanism and the electric motor;
• an inverter accommodation portion provided adjacent to the housing and accommodating the inverter;
• and
• a block body covering the target electronic component group in a posture of being attached to a circuit board of the inverter, formed in a block shape, and made of resin,
• wherein the circuit board has one surface which faces a bottom wall located on a housing side in the inverter accommodation portion and to which the target electronic component group is attached,
• the resin is thermoplastic resin,
• the inverter accommodation portion has a plurality of recessed portions formed in a portion of the bottom wall facing an end surface of the block body, and
• the block body has a plurality of protruding portions protruding from the end surface toward the bottom wall, each of the protruding portions being fitted in a corresponding one of the plurality of recessed portions facing each of the protruding portions.
