A heater device (25) includes: a base member (21H); a heater wire (26); and a sensor (24S) which measures capacitance of the heater wire, wherein the heater wire forms a first wiring pattern (21A1) and a second wiring pattern (21A2) 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.
