Abstract
A grain-oriented electrical steel sheet that includes a base coating with a high TiN ratio advantageous for the application of tension to the steel sheet and has excellent magnetic property is provided. The grain-oriented electrical steel sheet includes: a base coating having a peak value PTiN of TiN in the form of osbornite, observed in a range of 42°<2θ<43° and a peak value PSiOof SiOin the form of cristobalite, observed in a range of 23°<2θ<25° of both more than 0 and satisfying a relationship PTiN≥PSiO, in thin-film X-ray diffraction analysis; and an iron loss Wof 1.0 W/kg or less.
