ABSTRACT:
To provide a mold capable of manufacturing a metal-ceramic composite member in which a predetermined number of ceramic members are joined onto a large joining metal, the large joining metal being free from swell and shrinkage cavity on the surface thereof and high in dimensional precision. A metal-ceramic composite member3according to this embodiment is manufactured in such a manner that a predetermined number of metal-ceramic bonded substrates30are placed in a mold main body11constituting a mold1, with a ceramic substrate31side thereof facing upward, an atmosphere inside and outside the mold1is replaced with an inert gas such as a nitrogen gas from the atmosphere, a molten metal42is poured and filled in a first joining portion14that is formed by the molten metal main body11and an upper container13and that has a shrinkage cavity inducing portion16on a metal material holding portion side and a shrinkage cavity inducing portion18on an air vent side, and the molten metal42is cooled.
