できるのに対して、平板の両面の加熱は不合理であり、
熱効率上も無駄がある。When such a PTC heater is used for heating a floor material of a house or a flat material such as a wall surface, the heat generated from the PTC element is radiated to both sides through electrodes on both sides. This means that if only one side is heated from the viewpoint of the use characteristics of the floor and walls, the purpose can be sufficiently achieved, whereas heating of both sides of the flat plate is irrational,
There is waste in terms of thermal efficiency.

ある。The problem to be solved in the present invention is PTC
An object of the present invention is to find a means for solving the irrationality of double-sided heating when a conventional flat plate using elements is used as a floor material and a wall material.

特徴とする。According to the flat PTC heater of the present invention, the heat radiation side electrode is formed of a metal having good heat conductivity, and the other side electrode is compared with the metal forming the heat radiation side electrode. And is formed of a material having low thermal conductivity.

低い材料が選択される。[0007] The electrode of the PTC heater is required to have characteristics such as relatively high electric conductivity, excellent corrosion resistance, and good heat conductivity. In this sense, the electrode material used in the present invention is required. It is a matter of course that the material must satisfy the required characteristics. Among the materials satisfying the characteristics, a metal having good thermal conductivity and a material having low thermal conductivity are selected.

来の平板発熱体と比べ格段に多くなる。The heat generated by the PTC heating element increases the amount of heat radiation on the electrode side formed of a metal having good thermal conductivity, and the amount of heat radiation on the electrode side made of a material having low thermal conductivity on the other side has less heat radiation. This is dissipated on the electrode side formed of a metal having good thermal conductivity, and the amount of heat dissipated on one side is much larger than that of a conventional flat plate heating element.
