Abstract
A heater includes an insulating substrate, a heat generating section formed in the insulating substrate and including a plurality of divided regions in a longitudinal direction, temperature sensors detecting temperature of the heat generating section and a wiring pattern for power feed to the temperature sensors, each formed in a layer different from a layer in which the heat generating section is formed in the insulating substrate. The heat generating section, the temperature sensors, and the wiring pattern are layer stacked.
