Abstract: A method of manufacturing a hydrogen separation membrane with a carrier is characterized by including a first step of providing, between the hydrogen separation membrane and the carrier that supports the hydrogen separation membrane, a low-hardness metal membrane having a hardness that is lower than the hardness of the hydrogen separation membrane, and a second step of joining the hydrogen separation membrane, the low-hardness metal membrane, and the carrier by a cold joining method. In this case, it is possible to suppress the deformation of the hydrogen separation membrane, the low-hardness metal membrane, and the carrier and, as a result, it is possible to prevent damaging of the hydrogen separation membrane. The adhesion of the contact between the hydrogen separation membrane and the carrier is also improved. The result is that it is not necessary to increase the severity of the cold joining conditions.
