Abstract
The utility model relates to a heating plate. A conductive heating loop and an external insulation layer are arranged in order on the surface of a main body plate with properties of heat conduction and insulation from inside to outside. The conductive heating loop is formed by connection of at least one first conductive layer and at least one second conductive layer, wherein the direction of the at least one first conductive layer and the at least one second conductive layer are different; and the connection portions of the first conductive layer and the second conductive layer are overlapped to from an overlapped area. Besides, the conductive heating loop also includes at least two conductive segments convexly exposed outside the external insulation layer. Therefore, after currents are inputted at the conductive segments, the conductive heating loop can generate the heat energy rapidly; and the heat energy is transmitted to the main body plate by the heat-conducting insulation layer. In addition, because the overlapped area is formed at the turning portion of the conductive heating loop, the current bearing load can be increased, thereby solving a problem that the turning portion of the conductive heating loop is easily damaged.
