<p>PROBLEM TO BE SOLVED: To provide a floor heating heater increased in adhesiveness of a film while securing good PTC characteristics.SOLUTION: A floor heating heater 1 is a band-shaped long object, and configured by forming, on a film 11 on the lower surface thereof, a PTC ink layer 30 serving as a heating element having PTC characteristics, conducting wires 15a, 15b, and electrodes 13a, 13b and by bonding a film 17 to the upper surface thereof. The PTC ink layer 30 is formed in a band shape extending in a longitudinal direction of the heater, and a plurality of the PTC ink layers are disposed in a width direction of the heater with an interval therebetween. The film 17 on the upper surface is directly bonded to the film 11 on the lower surface, between the PTC ink layers 30, in addition to the PTC ink layers 30.</p> |
