Abstract
An electrical steel sheet used for a laminated core is an electrical steel sheet including an insulation coatingon a surface of a base steel sheet, the insulation coating being coated with a coating composition for an electrical steel sheet. The coating composition for an electrical steel sheet includes: an epoxy resin; an epoxy resin curing agent; and an elastomer-modified phenolic resin, in which the amount of the elastomer-modified phenolic resin is 10 parts by mass to 100 parts by mass with respect to 100 parts by mass of the epoxy resin.
