Zusammenfassung:	PROBLEM TO BE SOLVED: To further miniaturize a heat exchanger by improving piping density by reducing clearance gaps while spirally configuring heat exchange pipes.SOLUTION: This heat exchanger includes two heat exchange pipes 15, 16 configured by fixing one or a plurality of refrigerant pipes 12 in which a refrigerant is circulated, around a water pipe 11 in which water is circulated, each of the heat exchange pipes 15, 16 is spirally formed with a clearance gap between an inner periphery and an outer periphery of the spiral, and two heat exchange pipes 15, 16 are assembled into the double spiral shape by vertically fitting each of two heat exchange pipes 15, 16 to the clearance gap of the other spiral.
