PURPOSE:To position a laminated board constituting a multilayer wiring board accurately, and to facilitate easy mounting and fixing. CONSTITUTION:A positioning projecting section 8 composed of a truncated-cone- shaped thermoplastic resin is formed onto release paper 7, positioning ports are formed previously to copper-clad laminated boards 1, 3, 5 and prepregs 2, 14 laminated onto the release paper 7, and the laminated boards are positioned by the positioning projecting section 8 when the laminated boards are laminated. Each laminated board is unified under a positioned state by the thermoplastic resin by heating and pressing the laminated boards under a laminated state. Accordingly, a multilayer wiring board positioned accurately can be manufactured easily. |
