Abstract:

To provide an inexpensively constitutable sheet-like heater for a mirror excellent in reliability.

This sheet-like heater is composed of a pair of electrodes 21 each forming a comb-teeth shape, and arranged so that both comb teeth are alternately positioned each other, power supply terminals 22 respectively integrally formed on these electrodes 21, and a heating element layer 23 integrally molded with the electrodes 21 and the power supply terminals 22 so as to contain the electrodes 21, and composed of a conductive resin having a positive resistance temperature factor. Conventionally performed troublesome work such as installation of the power supply terminals by a eylet, and application of a resin for waterproofing the installing part is not required. Waterproofness is secured, and a problem (an obstruction) caused by corrosion is not caused.
