Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a steel sheet heating device in a continuous annealing furnace, in which the delay of heating control with respect to a prescribed target steel sheet temp. can be prevented. SOLUTION: In the heating device compensating the temp. of the steel sheet heated by the heating device mainly using a radiation heating in the continuous annealing furnace having a heating zone and a soaking zone, the heating device is disposed at the outlet side of the heating zone or at the intermediate part between the heating zone and the soaking zone, and one or more sets of electronic gun devices to scan in the sheet width direction, are arranged so as to be faced to the steel sheet.
