PROBLEM TO BE SOLVED: To effectively perform camber straightening of a sheet bar for preventing the deformation and damage of a induction heating device in the manufacturing method of a hot-rolled steel strip using hot-rolling equipment provided with the induction heating device for heating the sheet bar between a roughing mill and a finishing mill. SOLUTION: In the method for manufacturing the hot-rolled steel strip using the hot-rolling equipment which is provided with the roughing mill 2, a camber straightening device 5, the induction heating device 3 and the finishing mill 4 toward the downstream side from the upstream side, the camber straightening in the tip part of the sheet bar before conveying the sheet bar to the induction heating device 3 is performed in the process for conveying the sheet bar from the downstream side to the upstream side.
