PROBLEM TO BE SOLVED: To provide a sheet bar heating method for contriving to make the material quality of the sheet bar in the longitudinal direction even. SOLUTION: A heating temperature determination section 41 determines the heating temperature of the whole sheet bar 1 in the longitudinal direction based on a finish rolling speed pattern in order to secure the temperature at the outlet of a finish rolling mill. A heating temperature correction section 42 corrects temperatures at the front end and rear end of the sheet bar 1, out of the heating temperatures determined by the heating temperature determination section 41 based on the temperature of the front end of the sheet bar 1 measured by a thermometer 5, and sets the corrected temperatures onto a sheet bar heater 2. The sheet bar heater 2 heats the sheet bar 1 according to the set heating temperatures while tracking the advancing position of the sheet bar 1.
