摘要：
Provided are an insulation-coated oriented magnetic steel sheet having an insulating coat with excellent heat resistance; and a method for manufacturing the same. This insulation-coated oriented magnetic steel sheet has an oriented magnetic steel sheet, and an insulating coat arranged on the surface of the oriented magnetic steel sheet, the insulating coat containing Si, P, O, and Cr, and at least one element selected from the group consisting of Mg, Ca, Ba, Sr, Zn, Al, and Mn. The XPS spectrum of the outermost surface of the insulating coat has peaks observed at Cr2p 1/2 and Cr2p 3/2 .
