Abstract
A heating device has a plurality of strip heating portions separated by a plurality of slits. The strip heating portions are connected to one another by connecting portions, thereby forming a heating surface in which a zigzag current path extends. The connecting portions in which uneven-temperature regions exist are bent so as not to be positioned in the same plane as the heating surface, thereby making the heating surface, to be opposed to an object to be heated, to have a uniform temperature.
