PROBLEM TO BE SOLVED: To improve reliability such as durability while maintaining heating characteristics of the whole heating element by effectively arranging electrodes in a sheet-like heating element which can be used as a heat source for warming, heating and drying. SOLUTION: Since this sheet-like heating element has an electrically integrated structure wherein a plurality of polymer resistors 10, 13, 17 are connected with a lead wire, design constraint in arranging electrodes 6, 12, 16 of each heating part and resistors 7, 13, 17 can be reduced, the performance of the irregular shape sheet-like heating element can be sufficiently brought out, substrate waste loss can be abolished, and reliability such as durability can be improved.
