Abstract: The present invention makes it possible to prevent breakage such as cracking in a light-weight solar cell module. It is achieved by using a resin substrate solar cell module including a plurality of solar cells, a plurality of support posts disposed between the adjacent solar cells, and two transparent resin substrates, in which the plural solar cells and support posts are disposed between the two transparent resin substrates, a void section between the two transparent resin substrates is filled with a transparent filled resin, and peripheries of the two transparent resin substrates are welded with a resin having a repeating unit identical to the transparent resin substrates.
