1. A method for manufacturing a compressor including a tubular barrel, a stator core, and a resin member provided on an outer peripheral surface of the stator core, the method comprising:
fixing the stator core to an inside of the barrel via the resin member by shrink fit,
an outer peripheral surface of the resin member being a first joining surface and a surface in contact with the first joining surface on an inner peripheral surface of the barrel being a second joining surface, and
the fixing the stator core to the inside of the barrel including
joining the first joining surface to the second joining surface, and
upon joining, to the second joining surface, an intermediate portion of the first joining surface between a first end and a second end facing each other, spaces between the first joining surface and the second joining surface being formed
between the first end and the intermediate portion and
between the second end and the intermediate portion.
