Abstract
A production method for an aluminum-diamond composite having a step of providing a laminate structure including a composition layer containing a diamond powder in an opening of a flat plate-like porous material having the opening so as to be separated from an inner circumferential surface of the opening and a step of press-fitting a melt of a metal containing aluminum into a space between the porous material and the laminate structure and impregnating the composition layer with the melt to form a composited part containing aluminum and diamond and forming metal layers on at least side surfaces of the laminate structure, in which the laminate structure includes a first mold release plate, a first inorganic layer, the composition layer, a second inorganic layer and a second mold release plate in this order.
