    Resin of an ethylvinylacetate copolymer for a solar cell encapsulant sheet and the method for the manufacture thereof. An ethylene vinyl acetate copolymer resin (eva) used for a sheet of an encapsulant of a solar cell is provided, which has a reduced narrowing during the manufacture of the sheet and a low shrinkage rate during the thermal adhesion of a manufacturing process of the module and a method for the manufacture of the eva copolymer resin. The eva copolymer resin includes 25 to 33% by weight of a vinyl acetate monomer and has a z average molecular weight (mz) of 220,000 g/mol or less, a molecular weight distribution (mp/mn) in the range of 3.5 to 4.5, a melt flow index (mi) in the range of 6 to 35 g/10 min, measured at 190ºC under a load of 2.16 kg and a tan δ was measured using a rheometer at 100ºc, which satisfies the following formula: 1.85 * ln (mi)/(0.72 * in (frequency) 3.12) <tan δ <2.33 * ln (mi)/(0.72 * in (frequency) 2.81).
