A refrigerant pipe of a refrigeration apparatus includes: a first pipe, made of stainless steel, through which a refrigerant flows; a joint pipe, made of a material different from stainless steel, disposed on an outer peripheral surface of the first pipe; and a second pipe, having a diameter smaller than a diameter of the first pipe, connected to the outer peripheral surface of the first pipe via the joint pipe. A surface of the second pipe at which the second pipe is connected to the joint pipe is made of a material identical to the material of the joint pipe.
