Abstract: An electrical heating device includes supplemental heating means for supplementarily heating each of areas defined in advance in the material to be heated, and control means. A supplemental heating quantity for each of the areas is obtained by calculating a necessary heating quantity for heating each of the areas to a predefined target temperature and an electrical heating quantity generated in each of the areas by the electrical heating based on cross-sectional area information on the material to be heated and temperature information on the material to be heated and subtracting the calculated electrical heating quantity from the calculated necessary heating quantity. The control means controls, in addition to the control of an electrical heating, the supplemental heating means so that each of the areas is supplementarily heated based on the obtained supplemental heating quantity for each of the areas.
