To provide a method for manufacturing a hot-rolled steel strip for a grain oriented silicon steel sheet with excellent yield while preventing edge cracking and surface cracking generated when performing the hot rolling of a slab for the grain oriented silicon steel sheet.

A slab for a grain oriented silicon steel sheet containing, by mass, 0.01-0.08% C and 2.5-4.1% Si is heated in a gas heating furnace at 1,000-1,250C. Thereafter, the steel sheet is subjected to the edge-rolling with the reduction ratio of area at 2-15% by a caliber roll in which a part in contact with a corner part of the slab for the grain oriented silicon steel sheet forms the inclination of at least 30-60 with respect to the vertical line. In addition, the steel sheet is heated in an induction heating furnace at 1,250-1,450C, and subjected to the rough-rolling and the finish rolling.
