일 양태에 있어서, 전극에 대한 양호한 결착성을 확보하면서, 우수한 이온 투과성을 갖는 축전 디바이스 전극용 수지 조성물의 제공. 본 개시는, 일 양태에 있어서, 폴리머 입자를 포함하는 축전 디바이스 전극용 수지 조성물로서, 상기 폴리머 입자는, 이온 투과성을 갖고, 상기 폴리머 입자의 전해액에 의한 처리 전후에 있어서의 탄성 변화율 [(처리 후 탄성률)/(처리 전 탄성률)] 이, 30 ％ 이하인, 축전 디바이스 전극용 수지 조성물에 관한 것이다. One aspect provides a resin composition that is used for an electrode of a power storage device and that has excellent ion permeability while ensuring good binding properties with an electrode.One aspect of the present disclosure relates to a resin composition for an electrode of a power storage device. The resin composition contains polymer particles. The polymer particles have ion permeability. A rate of change in elasticity of the polymer particles before and after treatment with an electrolyte solution [(modulus of elasticity after treatment) / (modulus of elasticity before treatment)] is 30% or less.
