CORD-SHAPED HEATER AND SHEET-SHAPED HEATER

摘要

Provided is a cord-shaped heater (10), comprising a plurality of conducting wires (5a) which are covered with insulating films (5b). The insulating films (5b) further comprise a silicon resin. The quantity of the silicon resin included in the insulating films (5b) is 40-80% by weight ratio. The conducting wires (5a) are wound around a core material (3) in a state of being arrayed together in parallel. An insulation body layer (7), which is formed in whole or in part from a heat seal material, is formed on the outer circumference of the conducting wires (5a). Further provided is a sheet-shaped heater (31) wherein the cord-shaped heater (10) is disposed upon a substrate (11).
