A planar heat producing body (30) has parallel circuits (41-44) each formed by parallelly connecting heat producing resistor wires that produce heat by electricity. The parallel circuits are parallely extended while being adjacent to each other, and the adjacent parallel circuits are sequentially electrically connected in series to form a heater circuit. An area (105) where no heat producing resistor wire is placed and that extends in parallel to the parallel circuits is formed along at least one perimeter edge section of the planar heat producing body. Each parallel circuit is placed in a parallel circuit area having a width determined by (Ri/R) × W, where W is the overall width of the planar heat producing body including the area (105) having no heat producing resistor wire is placed in it, Ri is the electric resistance of each parallel circuit, and R is the total electric resistance of the heater circuit. Cette invention concerne un corps chauffant planaire (30) comprenant des circuits parallèles (41-44) formés de fils de résistance de chauffage à connexion parallèle qui produisent de la chaleur par alimentation électrique. Ces circuits sont adjacents et s'étendent parallèlement les uns aux autres, les circuits parallèles adjacents étant séquentiellement connectés en série pour former un circuit de chauffage. Une zone (105), où aucun fil de résistance de chauffage n'est placé et s'étendant parallèlement aux circuits parallèles, est formée le long d'au moins une section de bord périmétrique du corps chauffant planaire. Chaque circuit parallèle est placé dans une zone de circuit parallèle ayant une largeur déterminée par la relation (Ri/R) × W, où W est la largeur totale du corps chauffant planaire comprenant la zone (105) où aucun fil de résistance de chauffage n'est placé, Ri est la résistance électrique de chaque circuit parallèle, et R est la résistance électrique totale du circuit de chauffage.
