In a heater member executing a heat process with a heat subject placed thereon, and a heat processor using the same, the power supply is reduced to achieve energy conservation, a damage risk to be caused by the thermal stress is eliminated, and the wiring design flexibility is increased for a heat-generating circuit section. Furthermore, the heat uniformity capability is increased, and the reliability is increased by preventing short-circuit accidents.
At least entirely over the surface of a heat-subject-placing surface of a heater substrate 2, a low-radiation-rate film 10 made of a material whose radiation rate is lower than that of the heater substrate 2 is formed. By applying patterning to the low-radiation-rate film 10, the exposure rate of the heater substrate 2 is changed on the heat-subject-placing surface. Specifically, the radiation rate is varied in a manner such that the radiation rate becomes smaller from the center part of the heat-subject-placing surface toward the outer peripheral part thereof.
