A manufacturing method for a fluid pressure device and a fluid pressure device are provided, in which joints are diffusion bonded to a valve body. In the fluid pressure device, the joints are inserted into an inlet port and an outlet port formed in the valve body, and heating is performed to generate a temperature difference between the valve body and the joints, whereupon by diffusion bonding of the joints into a wall of the valve body in which the inlet port and the outlet port are formed, both members are bonded.
