Abstract: A panel heater includes: a heater main part including a substrate and an electric heating layer; an intervening terminal part including a base layer and a patterned conductive layer; and an anisotropic conductive film for coupling the heater main part and the intervening terminal part to electrically connect the electric heating layer to the conductive layer. The conductive layer is formed in a comb-shaped pattern including a plurality of tooth portions arranged in line at intervals and a portion connecting the tooth portions in common, the tooth portions being connected to the electric heating layer via the anisotropic conductive film, the intervening terminal part has a conducting wire-connective portion for connecting a power supply conductive wire to the conductive layer, and the electric heating layer and the conductive layer are made physically contact with each other via the anisotropic conductive film only by the tooth portions.

Abstract: It is to allow anisotropic conductive material to easily flow when an electric heating layer and a power supplying member for the heating layer are pressure-bonded via an anisotropic conductive layer, and to cope with various problems of temperature changes. A panel heater 2 comprising: a heater main part 2M comprising a substrate 21 and an electric heating layer 22; an intervening terminal part 2I including a base layer 23 and a patterned conductive layer 24; and an anisotropic conductive film 4 for coupling the heater main part 2M and the intervening terminal part 2I to electrically connect the electric heating layer 22 to the conductive layer 24.
