Abstract: A planar heating element according to the present invention is configured such that a pair of wires are inserted into a matrix formed by forming a base resin and a conductive material, so that heat is generated by means of electrical resistance that is generated inside the matrix when power is applied, wherein the planar heating element has a simple structure and is easy to manufacture and can achieve a sufficient heating effect regardless of thermal conductivity. In addition, the planar heating element is divided into a heating part and a non-heating part, and the heating part and the non-heating part are integrally manufactured through a double injection molding method. Thus, the present invention has advantages in that various shapes of planar heating elements can be manufactured and that manufacturing costs and manufacturing time can be reduced due to the manufacturing process being simple.
