A heat exchanger includes: a cylindrical member made of metal as an outer shell body; a corrugated fin that is made of metal and that is attached to the cylindrical member as a heat exchanging member; and a coating layer formed on at least one of a surface of the cylindrical member and a surface of the corrugated fin. The corrugated fin is pressure-contacted to the cylindrical member. The heat exchanger can be provided, for example, to a heat absorbing portion or a heat dissipating portion of a Stirling engine.
