PROBLEM TO BE SOLVED: To provide a method of manufacturing relay wiring boards, wherein utilization efficiency of a material is high and aligning the relay wiring boards is not required, when manufacturing the relay wiring boards. SOLUTION: In this method of manufacturing a multiple surface mounting relay wiring board composed of at least a heat resistant base material, an adhesive layer, and a protective film, all of the thickness of the heat resistant base material, all of the thickness of the adhesive layer, and a part of the thickness of the protective film are cut in the thickness direction from the heat resistant base material side. Thus, the relay wiring board is completely cut up to the heat resistant base material and the adhesive layer, and the protective film is not completely cut in its thickness direction.
