Zusammenfassung: | The objective of the present invention is to provide a joined body of dissimilar metals, in which a flared joint is formed and which have a high joint strength. The present invention is provided with a first metal member (11) having a curved surface portion (15), a second metal member (12) having a higher melting point than the first metal member (11) and joined to the first metal member (11) to form a flared joint, and a joining metal portion (13) formed by irradiating with a laser a filler material, disposed at the joint portion between the first metal member (11) and the second metal member (12), and the first metal member (11). The maximum thickness of an intermetallic compound (14) formed at the interface between the second metal member (12) and the joining metal portion (13) is at most 3 [mu]m. A melted portion (16) and a non-melted portion (17) are formed in the curved surface portion (15) of the first metal member (11) in which the flared joint is formed, in order in the thickness direction from the side on which the joining metal portion (13) is formed. |
