Abstract
A cord-shaped heater 10 has a plurality of conductive wires 5a that are covered with an insulating film 5b. The insulating film 5b includes a silicone resin. A quantity of the silicone resin included in the insulating film 5b is 40 to 80% by a weight ratio. The conductive wires 5a are wound around a core material 3 in a state of being paralleled together. An insulation body layer 7 is formed on an outer periphery of the conductive wires. A part or all of the insulation body layer 7 is formed of a heat-fusing material. A sheet-shaped heater 31 is wherein the cord-shaped heater 10 is arranged on a substrate 11.
