摘要： A treatment solution is applied on a surface of a base iron; and the treatment solution is baked and dried. The treatment solution contains a first component: 100 parts by mass in solid content, and a second component composed of particles of one or more kinds selected from a group consisting of a polyolefin wax, an epoxy resin and an acrylic resin, the particles having an average particle size of 2.0 μm to 15.0 μm and a melting point of 60° C. to 140° C.: 5 parts by mass to 45 parts by mass in resin solid content. The first component contains a colloidal silica: 100 parts by mass, and an emulsion of 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 an emulsion of a mixture or copolymer of two or three kinds selected from the group: 40 parts by mass to 400 parts by mass in resin solid content.

摘要： A silicon steel sheet (1) containing Si is cold-rolled. Next, a decarburization annealing (3) of the silicon steel sheet (1) is performed so as to cause a primary recrystallization. Next, the silicon steel sheet (1) is coiled so as to obtain a steel sheet coil (31). Next, an annealing (6) of the steel sheet coil (31) is performed through batch processing so as to cause a secondary recrystallization. Next, the steel sheet coil (31) is uncoiled and flattened. Between the cold-rolling and the obtaining the steel sheet coil (31), a laser beam is irradiated a plurality of times at predetermined intervals on a surface of the silicon steel sheet (1) from one end to the other end of the silicon steel sheet (1) along a sheet width direction (2). When the secondary recrystallization is caused, grain boundaries passing from a front surface to a rear surface of the silicon steel sheet (1) along paths of the laser beams are generated.
