摘要

PURPOSE:To prevent the formation of bulging of a metal plate by providing plural through holes or the groove passing to the end face on a metal plate via a gap and joining to the base body composed of a metal or ceramics. CONSTITUTION:In case of joining a metal plate 10 and the base body 12 composed of a metal plate or ceramics by the molten body due to a heating eutectical reaction plural through holes 11 or the groove passing to the end face is formed at certain or uncertain intervals on the metal plate 10. The molten body formed on the joining interface is pushed out the gas inside the gap at the process spreading with wetting on the joining face of both members 10, 12. In this case, the pushed out gas is pushed out to the outside of the joining part via the through hole 11 or groove 16, so the formation of the bulging on the metal plate 10 in a high temp. state is prevented.
