PURPOSE: A solar cell module manufacturing method is provided to simplify a manufacturing process of a solar cell module and to embody a compact the solar cell module. CONSTITUTION: A reflection protect layer is formed on the one side of a transparent substrate(S100). A circuit pattern is formed on the one side of the transparent substrate(S200). A junction layer is formed on the one side of the transparent substrate in order to be exposed a part of the circuit patterns(S300). A conductive bump is formed on the circuit pattern(S400). The transparent substrate and a solar cell are welded for welding a conductive pad which is formed in the one side of a bump and the solar cell(S500). A protection resin layer is formed on the one side of the transparent substrate for covering the solar cell(S600).
