PROBLEM TO BE SOLVED: To provide a manufacturing method of a composite plate that can surely bond a bonding sheet body, where a metal protrusion section is attached to the surface of a metal substrate. SOLUTION: In this method, the composite plate is manufacture, where the composite plate has a bonding sheet body 1, a metal protrusion section 2 attached onto the surface of the bonding sheet body 1, and a metal pedestal 4 having a hollow section 3 inside. While the metal protrusion section 2 is being laminated onto the surface of the bonding sheet body 1, the bonding sheet body 1 is laminated onto the surface of the metal pedestal 4 via a bonding material S. They are surrounded by a packing bag 13, having a heat resistance and breathing resistance. The inside of the packing bag 13 is set to a reduced pressure state. In the reduced pressure state, the hollow section 3 of the metal pedestal 4 communicates with the outside of the packing bag 13 in the chamber, and at the same time, the packing bag 13 is heated and pressurized.
