A grain oriented electrical steel sheet includes a base steel sheet, a glass film, and a tension-insulation coating. When a glow discharge emission spectroscopy is conducted from a surface of the glass film toward a depth direction, an analysis starting time Ts, a time TAlp at which Al shows a maximum emission intensity, an Al emission intensity F(TAlp) at the TAlp, a time TSip at which Si shows a maximum emission intensity, and an Al emission intensity F(TSip) at the TSip satisfy 0.05≤F(TSip)/F(TAlp)≤0.50 and 2.0≤(TAlp−Ts)/(TSip−Ts)≤5.0.
