The joined body contains a first metal member having a curved surface portion, a second metal member having a higher melting point than the first metal member and joined to the first metal member to form the flared joint, and a joining metal portion formed by irradiating the first metal member and a filler material disposed between the first and second metal members with a laser. An intermetallic compound formed at the interface between the second metal member and the joining metal portion has a thickness of at most 3 μm. A melted portion and a non-melted portion are formed in the curved surface portion of the first metal member in which the flared joint is formed.
