PLANAR HEAT-GENERATING BODY AND METHOD FOR MANUFACTURING SAME

摘要

A self-temperature-controlling-type planar heat-generating body mounted on the back surface of a mirror, wherein a satisfactory defogging performance and a satisfactory long-term heat-generating performance can be obtained. This invention is provided with a base film (21), electrodes (22, 23) formed by patterning an aluminum foil on the base film (21), an electroconductive coating (24) formed on the surface of the electrodes (22, 23), and a PTC heat-generating body film (25) formed so as to cover the electrodes (22, 23) with the electroconductive coating (24) interposed therebetween. The electroconductive coating (24) has a configuration in which an electroconductive material is mixed into a phenol resin or an epoxy resin.
