PROBLEM TO BE SOLVED: To provide a planar heater which is easily applied to any shape of the surface to be heated by forming a plurality of trapezoidal or square projections in parallel on one surface of a plane rubber-like elastic body and burying a heating wire in the projection. SOLUTION: A heating wire is buried in the projection of a rubber-like elastic body, a space is formed between the projections which are parallel to each other to give flexibility to a surface heater, and thereby, the surface heater can easily be fit to the curved surface even if a substance to be heated has a curved surface. By burying the heating wire in the projection, heat is efficiently transmitted to the substance to be heated. By giving magnetic property to the rubber-like elastic body or forming a magnet layer or an adhesive layer on the top surface of the projection, the surface heater is easily, surely attached to the substance to be heated. As the rubber-like elastic body, silicone rubber, fluorine rubber or the like is used. For example, a heating wire 8 is buried in a projection 2 having a magnet layer 9 of a planar heater 5. |
