Abstract: A silicon steel sheet (1) containing Si is cold-rolled. Next, a decarburization annealing (3) of the silicon steel sheet (1) is performed so as to cause a primary recrystallization. Next, the silicon steel sheet (1) is coiled so as to obtain a steel sheet coil (31). Next, an annealing (6) of the steel sheet coil (31) is performed through batch processing so as to cause a secondary recrystallization. Next, the steel sheet coil (31) is uncoiled and flattened. Between the cold-rolling and the obtaining the steel sheet coil (31), a laser beam is irradiated a plurality of times at predetermined intervals on a surface of the silicon steel sheet (1) from one end to the other end of the silicon steel sheet (1) along a sheet width direction (2). When the secondary recrystallization is caused, grain boundaries passing from a front surface to a rear surface of the silicon steel sheet (1) along paths of the laser beams are generated.
