PURPOSE: To uniformalize heating temperature or temperature distribution by making distribution of heating temperature controllable by arranging a high conductive region such as a strip-like high conductive body in the way as not to cross terminal electrodes in a plain heating element employing a plain resistor. CONSTITUTION: In a plain heating element composed of a plain resistor 1 and a pair of electrodes 4a, 4b connected with the plain resistor 1; at least one high conductive region 3 is so formed in the plain resistor 1 (the figure b) or on the plain resistor 1 (the figure a) as not to cross the electrodes 4a, 4b. As the resistor 1, for example, an insulating substrate 2 made of a thermally plastic resin and on which a prescribed pattern of a conductive resin composition is formed can be employed. The high conductive region 3 may be a strip-like pattern formed by sticking a conductive tape, e.g. a copper tape to the plain resistor 1 or applying a conductive paste, e.g. a silver paste to the plain resistor 1. |
