PURPOSE: A sealing film for a solar cell module and a method for producing the sealing film are provided to avoid the distortion causing the damage of a solar cell and positional deviation. CONSTITUTION: A solar cell module is assembled by: laminating a web(2) and a liner(4) consisting of an ethylene-based copolymer and a crosslinking agent; returing the web and line; heating the web; and performing an embossing process. When the solar cell module is heated and crosslinked, the values in the longitudinal direction and the transverse direction of the film are not changed. The heating temperature if 90°C - 125°C.
