NOVELTY - The invention claims a self-heating plate, comprising a heating component layer, plank component layer on the front surface of the layer and the heating component layer back surface of the insulating layer; the heating component layer comprises two layers of flame-retardant insulating films and graphene frame located between the two layers of flame-retardant insulating films; the flame-retardant insulating film is respectively with the corresponding plank layer and the insulating layer; the heating film graphene connected with the conductive frame, the conductive frame is provided with a power supply joint; the plate surface of the insulating layer and the flame-retardant insulating film connected with the insulating layer are provided with avoiding through holes for exposing the power supply joint. The power supply joint assembly in the invention passes through the insulating layer external power supply, solves the problem of the wire leakage, at the same time, because the electric wire does not leak from the edge of the plate, it is convenient for edge sealing processing of the plate, suitable for desk and desk field.
