Abstract
In order to improve uniformity of temperature distribution, despite heat which is generated in a resistance circuit and flows into a support part thereby causing a high output, a resistance circuit is provided with first, second and third regions having different resistance values so that the third region which is in proximity to the support part has the highest resistance value.
