Claim 7:
8. The grain oriented electrical steel sheet according to claim 1, wherein
when (α, β, and γ) are defined as deviation angles from the ideal Goss orientation based on the rotation axis, parallel to the normal direction Z, parallel to the transverse direction C and parallel to the rolling direction L, respectively, of the crystal orientation measured at each measurement point among the at least 500 measurement points on the sheet surface, and θ=[α2+β2+2]1/2 is defined as a deviation angle at each measurement point,
σ(θ) which is a standard deviation of an absolute value of the deviation angle θ is 0° to 3.0°.
