PROBLEM TO BE SOLVED: To provide a manufacturing method of a powder-containing ethylene oxide copolymer resin, comprising an ethylene oxide copolymer and a powder mixed with and dispersed in the copolymer, that suffers from no decrease in molecular weight of the resin by mechanical shear or the like, and a packaging method of the resin obtained by the same. SOLUTION: The manufacturing method comprises a step where a powder containing an electrochemically active substance is mixed with and dispersed in an ethylene oxide copolymer resin solution comprising an ethylene oxide copolymer resin, comprised of 80-95 wt.% of ethylene oxide and 5-20 wt.% of an oxirane compound copolymerizable with ethylene oxide, and a solvent thereby to give a powder-containing ethylene oxide copolymer resin solution, a step where the solvent is removed from the powder-containing ethylene oxide copolymer resin solution thereby to give a flowable powder-containing ethylene oxide copolymer resin, a step where the flowable powder-containing ethylene oxide copolymer resin is pelletized or granulated, and a step where the pelletized or granulated powder-containing ethylene oxide copolymer resin is dried.
