GRAIN-ORIENTED MAGNETIC STEEL SHEET, STEEL SHEET FOR FINISH ANNEALING, ANNEALING SEPARATING AGENT, METHOD FOR MANUFACTURING GRAIN-ORIENTED MAGNETIC STEEL SHEET, AND METHOD FOR MANUFACTURING STEEL SHEET FOR FINISH ANNEALING
Grain-oriented electrical steel sheet excellent in magnetic properties and adhesion of a primary coating to a base steel sheet and with few defects where the base metal is exposed in point defects and a method for manufacturing grain-oriented electrical steel sheet are provided. This is characterized by being provided with a base steel sheet and a primary coating. The primary coating satisfies (1) Number density D3 of Al concentrated regions: 0.015 to 0.150/µm2, (2) (Area S5 of regions comprised of anchoring oxide layer regions and Al concentrated regions)/(area S3 of Al concentrated regions)≥0.30, (3) Distance H5 of mean value of heights in thickness direction of regions of comprised of anchoring oxide layer regions and Al concentrated regions minus H0: 0.4 to 4.0 µm, (4) (Perimeter L5 of regions comprised of anchoring oxide layer regions and Al concentrated regions)/(observed area S0): 0.020 to 0.500 µm/µm2, and (5) (Area S1 of anchoring oxide layer regions)/(observed area S0)≥0.15.
