Abstract: The present invention provides a grain-oriented electrical steel sheet with an extremely low core loss by scanning by a small focused laser beam spot and a method of production of the same, that is, a grain-oriented electrical steel sheet improved in electrical characteristics by scanning by a continuous wave fiber laser of the TEM00 mode with a wavelength ? of 1.07???2.10 ?m substantially perpendicular to the steel sheet rolling direction and at substantially constant spacing and a method of production of the same, wherein a rolling direction focused spot diameter d (mm) of the irradiated beam, a linear scan rate V (mm/s) of the laser beam, an average output P (W) of the laser, a width of the formed laser scribing traces or with of the electrical domains Wl (mm), and a rolling direction Pl (mm) of the laser scribing traces are in the following ranges: 0<d?0.20 0.001?P/V?0.012 0<Wl?0.20 1.5?Pl?11.0.
