摘要： An electrical steel sheet is provided which is capable of improving heat conductivity. The electrical steel sheet includes: a steel strip (1) for an electrical steel sheet; and an insulating film (2) formed at a surface of the steel strip (1) and containing metal phosphate and organic resin. At least a part of the metal phosphate includes at least one kind of crystal structure selected from a group consisting of a cubic system, a tetragonal system, a hexagonal system, and an orthorhombic system. The organic resin contains at least one kind selected from a group consisting of an acryl-based resin, an epoxy-based resin, and a polyester resin having a carboxyl group or a hydroxyl group at a surface of an emulsion particle for one part by mass to 50 parts by mass relative to 100 parts by mass of the metal phosphate.
