PROBLEM TO BE SOLVED: To provide a preform capable of suppressing the occurrence of a pore and a void to be caused in a manufactured composite, in a metal-ceramic composite obtained by pressureless infiltration of a metal as a base material into the preform in which a ceramic serves as a reinforcing material, and to provide a metal-ceramic composite using the preform, and a method for manufacturing the metal-ceramic composite.SOLUTION: A preform for obtaining a metal-ceramic composite has a molten metal retaining part in which molten metal is reserved when the preform with molten metal infiltrating thereinto is pulled up from molten metal, wherein the molten metal retaining part is preferably at least one depressed or raised portion. A metal-ceramic composite using the preform and a method for manufacturing the metal-ceramic composite are provided. |
