Abstract: Provided is a process of producing a solar battery module 1 including plural solar battery cells 4 sealed by a resin 5 between a transparent panel 2 of the light reception surface side and a back face panel 3, which is characterized by arranging plural solar battery cells 4 at a prescribed interval and mutually connecting them to each other by a conductor 8; arranging a first sealing resin sheet 12 substantially covering the entire surface of the transparent panel 2 of the light reception surface side between the transparent panel 2 of the light reception surface side and the solar battery cells 4; arranging a second sealing resin sheet 10 substantially covering the entire surface of the back face panel 3 between the back face panel 3 and the solar battery cells 4; arranging sealing resin sheet pieces 18, 19 which are thicker than the solar battery cells 4 at a space 9 between the solar battery cells 4 so as to be sandwiched by the first sealing resin sheet 12 and the second sealing resin sheet 10; dischargin
