Patent ID: 7847216

Claim:
A panel heater comprising: a heater main part comprising a substrate and an electric heating layer deposited thereon; an intervening terminal part including a base layer and a patterned conductive layer supported by the base 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, wherein: the conductive layer is formed in a comb-shaped pattern including a plurality of tooth portions arranged in line in a predetermined direction 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 conducting wire for transmitting electric power to be supplied to the electric heating layer to the comb-shape-patterned 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, wherein the tooth portions are divided into groups each constituted by a plurality of teeth, and the base layer has individual areas supporting these groups respectively, the individual areas being separated by a space.
