This resin for energy device electrode contains structural units derived from a nitrile group-containing monomer and structural units derived from a monomer represented by formula (I), and does not contain structural units containing a carboxyl group derived from a carboxyl group-containing monomer, or the ratio of the structural unit containing a carboxyl group derived from a carboxyl group-containing monomer with respect to 1 mol. of the structural units derived from a nitrile group-containing monomer does not exceed 0.01 mol., and the ratio of the structural units derived from a nitrile group-containing monomer as a percentage of the total of the structural units derived from each monomer is 90% or greater but less than 100%. Here, in formula (I), R1 represents a hydrogen atom or a methyl group, R2 represents a monovalent hydrocarbon group, and n is an integer from 1 to 50.
