PROBLEM TO BE SOLVED: To provide a line and a method of manufacturing a steel plate by which the temperature inhomogeneity of a thick steel plate, in particular the temperature inhomogeneity in the width direction, is reduced and the steel plate having good flatness is obtained in a natural cooling stage after cooling by heating the plate by suppressing the power consumption for induction heating. SOLUTION: In a line 100 of manufacturing the steel plate on which a cooling system 10, an induction heating device 50 and a first shape correcting device 20 are arranged in this order, a second shape correction device 30 is arranged between the cooling system 10 and the induction heating device 50.
