ABSTRACT:
A process of producing a metal base laminate plate wherein the productivity and the yield are high. The process comprises the steps of applying an insulator film by powder coating to a metal plate having a through-hole formed therein to form a metal base plate, placing a film base plate having a heat resisting property in position on the metal base plate with a thermosetting adhering sheet interposed therebetween, pressurizing and heating part of a layered body consisting of the metal base plate, adhering sheet and film base plate to temporarily adhere the metal base plate and the film base plate to each other, and introducing the layered body in a predetermined orientation into a pair of pressuring and heating rollers to finally adhere the metal base plate and the film base plate to each other. When a layered body of a metal base plate and a film base plate passes the pressurizing and heating rollers, air is driven out of them. Consequently, little air bubbles remain in a metal base laminate plate produced by the process.
