ABSTRACT:
A grain-oriented electrical steel plate is characterized in that grooves having a width of 10 μm to 200 μm and a depth of 10 μm to 30 μm exist in at least one of a front surface and a rear surface of a steel plate at intervals of 1 mm to 10 mm, an angle between a direction in which the grooves extend and a rolling direction of the steel plate is 60 degrees to 120 degrees, and tensile stresses having a maximum value of 20 MPa to 300 MPa act in the rolling direction within ranges of 10 μm to 300 μm from side surfaces of the grooves.
