An object of the present invention is to provide a method for producing a resin composition for solar cell sealing material which is capable of lowering a cost by shortening of a processing time and has good storage stability. Further, another object of the present invention is to provide a solar cell sealing material having excellent transparency due to no generation of lumps therein by using the obtained resin composition for solar cell sealing material. A method for producing a resin composition for solar cell sealing material according to the present invention includes: preparing an ethylene-vinyl acetate copolymer (A) containing a vinyl acetate unit in an amount of 25 to 35 wt% and a crosslinking agent (B), whose impregnation weight with respect to 1 g of the ethylene-vinyl acetate copolymer (A) per 24 hours at a temperature of 23°C is in the range of 40 to 80 mg, as raw components; and impregnating the crosslinking agent (B) into the ethylene-vinyl acetate copolymer (A) at a temperature of 15 to 80°C.
