PURPOSE: A wire structure of a capillary net heating sheet is provided to extend a length of a heating plate with the minimum power by forming wires in parallel and in series between one heating sheet and other neighboring heating sheet. CONSTITUTION: Wires of a plurality of heating sheets(2a,2b,2c,2d) are arranged in parallel. Upper ends(18a,18b) and lower ends(18c,18d) of power wires(14,16) are formed inside the heating sheets(2a,2b,2c,2d) and are connected. A connector is formed on a predetermined part of a center of connecting wires of the heating sheets(2a,2b,2c,2d). An upper end connecting wire of the heating sheet(2a) is connected by the second connecting wire(22) and an upper end connecting wire of the heating sheet(2b). A lower connecting wire of the heating sheet(2a) is connected by the third connecting wire(22) and a lower end connecting wire of the heating sheet(2b). In consequence, the adjacent heating sheets(2a,2b) are connected in parallel to each other. The second connecting wire(22) is connected by the third connecting wire of the lower end of the heating sheets(2c,2d), whereby the wires are connected in series. Separate connectors(26a,26d) are formed on each connecting wire for connecting one set of heating sheets(2a,2b) and the other set of heating sheets(2c,2d).
