A refrigerant pipe (R2) of a refrigeration apparatus includes: a first pipe (23) made of stainless steel through which a refrigerant flows; a joint pipe (40) provided on an outer peripheral surface of the first pipe (23) and made of a material different from stainless steel; and a second pipe (50, 51) having a diameter smaller than that of the first pipe (23) and connected to the outer peripheral surface of the first pipe (23) via the joint pipe (40). A surface to be connected (51b) of the second pipe (50, 51) to the joint pipe (40) is made of an identical material to the material of the joint pipe (40).
