To provide a heater wire and a planar heater that can prevent disconnection and have good heating efficiency.SOLUTION: A heater wire 3a includes a resistance wire that is made of a SUS wire (stainless steel wire), in which a child stranded wire made of a plurality of hard SUS wires is arranged at the center and a child stranded wire made of a plurality of soft SUS wires are arranged on the outer periphery, respectively and these are composite-twisted. A planar heater 1 is arranged on a vehicle seat 11 including a seat center portion 13 and a side support portions 15 (bolster portion) formed by being raised on both the left and right sides of the seat center portion 13, and the seat heater 1 includes base materials 5a and 5b, and heater wires 3a and 3b arranged on the base materials 5a and 5b. In a portion arranged in the seat center portion 13, the heater wire 3b having the resistance wire made of a copper wire or a copper alloy wire is arranged. In a portion arranged in the side support portion 15, the heater wire 3a having a resistance wire made of SUS wire is arranged.SELECTED DRAWING: Figure 2

    【課題】断線を防止でき、採暖の効率が良いヒータ線と面状ヒータを提供すること。【解決手段】複数の硬質SUS線からなる子撚線を中心とし、その外周に複数の軟質SUS線からなる子撚線を配置し、これらを複合撚りした構成したSUS線(ステンレス鋼線)からなる抵抗線を有するヒータ線3a。シートセンター部13と、該シートセンター部13の左右両側に盛り上げられて形成されたサイドサポート部15(ボルスター部)とを有する車両シート11に配置され、シートヒータ1は、基材5a,5bと基材5a,5b上に配設されたヒータ線3a,3bとからなり、シートセンター部13に配置される部分においては、銅線又は銅合金線からなる抵抗線を有すヒータ線3bが配設され、サイドサポート部15に配置される部分においては、SUS線からなる抵抗線を有すヒータ線3aが配設される面状ヒータ1。【選択図】図2
