1. A method for manufacturing a plate-type heater, comprising, manufacturing an upper component and a lower component composed of joined outer coverings and intermediate layers;applying a heating element to the upper part of the entire surface of the lower component; andattaching wires, used to supply electrical energy, by lamination, to the ends of the heating element, andjoining the lower component to which the heating element has been applied, to the upper component,in which the joining of the outer coverings and intermediate layers is carried out by extrusion lamination using a polyolefin resin. 2. The method for manufacturing a plate-type heater according to claim 1, in which the joining of the outer covering and intermediate layer is carried out by extrusion lamination using a polyolefin resin having a melting point of from about 100° C. to about 170° C. 3. The method for manufacturing a plate-type heater according to claim 1 in which the application of the heating element is carried out by gravure lamination printing. 4. The method for manufacturing a plate-type heater according to claim 3, in which the gravure lamination is carried out using a gravure printing roller mesh size of about 80# to about 150#. 5. The method for manufacturing a plate-type heater according to claim 1, in which adhesion of the wires is carried out by fusion bonding with polyolefin resin. 6. The method for manufacturing a plate-type heater according to claim 1, in which the thickness of the wires is adjusted to manufacture products having a width of 1 meter or more without cutting. 7. The method for manufacturing a plate-type heater according to claim 1, in which the lamination process used is extrusion lamination. 8. A plate-type heater, comprising an upper component comprising a first outer covering and a first intermediate layer;a lower component comprising a second outer covering and second intermediate layer;said first outer covering and said first intermediate layer joined together by a polyolefin resin using an extrusion coating process;said second outer covering and said second intermediate layer joined together by a polyolefin resin using an extrusion coating process;a heating element comprising a first carbon compound layer, in a hardened form, placed between the upper component and the lower component and a second carbon compound layer laminated on the first carbon compound layer by gravure printing;conductive wires fusion bonded to both ends of the second carbon compound layer by lamination, without an adhesive, so that when electricity is passed to the conductive wire, the entire carbon compound layers are heated. 9. The plate-type heater of claim 8, in which the carbon compound is composed of a mixture of a urethane polymer resin, a conductive powder, additives, and a diluent solvent. 10. The plate-type heater of claim 8, in which the first intermediate layer and second intermediate layer are composed of a non-woven fabric, paper, or cotton. 11. The plate-type heater of claim 8, in which the first outer covering and second outer covering are selected from polyethylene, polypropylene, and nylon.
