摘要： A resin for an energy device electrode contains a structural unit derived from a nitrile group-containing monomer; and a structural unit derived from a monomer represented by the following Formula (I), wherein the resin does not contain a structural unit that is derived from a carboxy group-containing monomer and that contains a carboxy group, or the resin has a ratio of a structural unit that is derived from a carboxy group-containing monomer and that contains a carboxy group of 0.01 moles or less with respect to 1 mole of the structural unit derived from a nitrile group-containing monomer, and a ratio of the structural unit derived from a nitrile group-containing monomer to a total of structural units derived from each monomer is from 90% by mole to less than 100%.
