A heating plate includes a thermally conductive, electrically insulating main board on whose surface an electrically-conductive heat-generating circuit and an outer insulating layer are layered. The heat-generating circuit is formed by connecting one first electrically-conductive layer and one second electrically-conductive layer that are arranged in different directions. The first and second electrically-conductive layers are overlapped to form an overlapping area. The heat-generating circuit has at least two electrically-conductive segments exposed outside the outer insulating layer. Thereby, when the electrically-conductive segments receive incoming current, the electrically-conductive heat-generating circuit can generate heat rapidly, and the heat can be transmitted to the main board through the thermally-conductive insulating layer. The overlapping area formed at each turning point along the electrically-conductive heat-generating circuit is more capable of load bearing so that the electrically-conductive heat-generating circuit is unlikely to be damaged at the turning point. |
