PROBLEM TO BE SOLVED: To provide such a brazed object that a brazing filler metal is sufficiently held to a brazing objective member in coupling and fixing the brazing objective member to a base or the like, and such a valve assembly that prevents fluid from leaking to the outside of the valve assembly. SOLUTION: The brazed object of the brazing objective member comprises fixing fluid outflow pipes 28a, 28b, which are made of metal and a valve body support shaft 35 composed of a metallic material whose activation temperature is higher than that of the pipes, in proximity to each other to a valve seat plate 13 for supporting the pipes and the valve body support shaft 35 by the use of the brazing filler metal. A metallic member 20 having the small heat capacity and reaching the activation temperature at the same time or earlier than the outflow pipes 28a, 28b is arranged in a shaft hole 13e to be made into a brazing portion formed by the valve body support shaft 35 and the valve seat plate 13, and the valve body spindle 35 is brazed and fixed to the valve seat plate together with the metallic member 20 of the small heat capacity.
