Claim Text:
1. A grain oriented electrical steel sheet having a forsterite coating and tension coating on a surface thereof and having plastic strain extending in a direction inclined by 45° to 90° with respect to the rolling direction, wherein: the forsterite coating is formed by coating a surface of the steel sheet with 10.0 g/m total tension in a rolling direction imparted to the steel sheet by the forsterite coating and the tension coating is equal to or higher than 15 MPa, total tension in a direction orthogonal to the rolling direction imparted to the steel sheet by the forsterite coating and the tension coating is equal to or higher than 5.0 MPa; and the total tension in the rolling direction and the total tension in the direction orthogonal to the rolling direction satisfy A: the total tension in rolling direction imparted to the steel sheet by forsterite coating and tension coating, and B: the total tension in a direction orthogonal to the rolling direction imparted to the steel sheet by forsterite coating and tension coating.
