Abstract
To provide a refrigerant pipe, a manufacturing method of a refrigerant pipe, connection structure for refrigerant pipes, and a valve device that it is easy to perform connection by brazing even in a case in which the materials thereof are different from each other. A joint member consists of stainless steel, wherein a coat of copper or copper alloy by a metallic bond is formed on an inner circumferential surface or an outer circumferential surface in an end portion on at least one side in a longitudinal direction. Accordingly, even in the case in which the joint member itself consists of stainless steel, it is easy to connect with the connection target via the end portion on which the coat of copper or copper alloy is formed.
