Abstract
A method for manufacturing a multilayer laminate provides in metal plates each forming a substrate apertures at positions where through holes are to be formed, fills the apertures with a synthetic resin including a first filler, and prepares prepregs to be disposed on both sides of each substrate by impregnating nonwoven fabric with a thermosetting synthetic resin containing a second filler. The metal plates forming the substrates are thereby allowed to be thicker for realizing larger capacity power supply with an improvement also in heat dissipation characteristics.
