Abstract:
An electrical steel sheet (10) is provided with a base iron (1) and an insulating film (2) formed on a surface of the base iron (1). The insulating film (2) contains: a first component: 100 parts by mass, the first component containing: a metal phosphate: 100 parts by mass; and one kind selected from a group consisting of an acrylic resin, an epoxy resin and a polyester resin which have an average particle size of 0.05 μm to 0.50 μm, or a mixture or copolymer of two or three kinds selected from the group: 1 part by mass to 50 parts by mass; and a second component composed of dispersion or powder of a fluorine resin having an average particle size of 0.05 μm to 0.35 μm: 0.5 parts by mass to 10 parts by mass.
