NOVELTY - Manufacture of electric current collector sheet (2) involves performing back surface protective layer (23) integration process, circuit (24) formation process and insulation layer (22) forming process. Integration of back surface protective layer involves integrally-forming back surface protective layer which becomes back surface side of resin base material (21). Circuit formation involves forming circuit consisting of metal on resin base material. Formation of insulation layer involves coating curing insulation ink on the circuit, and irradiating the ink using ultraviolet ray.    USE - Manufacture of electric current collector sheet used for solar cell module (claimed).    ADVANTAGE - The method enables manufacture of electric current collector sheet of integrated-type back surface protective layer which suppresses the curl-form deformation.    DETAILED DESCRIPTION - Manufacture of electric current collector sheet involves performing back surface protective layer integration process, circuit formation process and insulation layer forming process. Integration of back surface protective layer involves integrally-forming back surface protective layer which becomes back surface side of resin base material formed from resin sheet. Circuit formation process involves forming circuit consisting of metal on the surface of resin base material. Formation of insulation layer involves coating ultraviolet curing insulation ink on the circuit, and irradiating the curing insulation ink using ultraviolet ray. During ultraviolet irradiation, the heating process is carried out at 90-110 degrees C for 10-40 seconds. The electric current collector sheet is located on back side of solar cell element (1) of back-contact type as internal wiring for solar cell module. An INDEPENDENT CLAIM is included for solar cell module.
