PROBLEM TO BE SOLVED: To provide an electric heating device of plated metal plate for hot stamp capable of reducing deviation of a plating layer, by reducing the Lorentz force acting on a molten plating layer compared with a conventional electric heating device.SOLUTION: An electric heating device 10 includes first and second auxiliary electrification plates 12, 13 having the same planar shape as that of a plated metal plate 11, a power supply 15 for electrifying the plated metal plate 11, and an adjust current supply unit (second power supply 16) for supplying a current, larger than 1/2 of the magnitude of a current flowing to the plated metal plate 11 and flowing reversely therefrom, to the first and second auxiliary electrification plates 12, 13, respectively. The first and second auxiliary electrification plates 12, 13 are arranged oppositely to the first and second surfaces of the plated metal plate 11, respectively, in parallel with the plated metal plate 11.SELECTED DRAWING: Figure 2A |
