Abstract: A heater device includes: a base member; a heater wire; and a sensor which measures capacitance of the heater wire, wherein the heater wire forms a first wiring pattern and a second wiring pattern connected in series, the first wiring pattern and the second wiring pattern each include N wire blocks, the N wire blocks included in the first wiring pattern and the second wiring pattern are disposed in a manner that arrangement of the N wire blocks included in the first wiring pattern and arrangement of the N wire blocks included in the second wiring pattern are reversed in the circumferential direction of the rim and facing each other in a direction perpendicular to the circumferential direction, and a sum of sensitivity of the sensor to capacitance of a pair of wire blocks facing each other is substantially equal to that of another pair.
