Abstract
A heater device includes a heat generating part that generates heat by energization, and a detection unit. The detection unit detects whether or not a distance between an object around the heat generating part and the heat generating part is equal to or less than a first detection distance with a first detection sensitivity, and whether or not the distance between the object around the heat generating part and the heat generating part is equal to or less than a second detection distance shorter than the first detection distance with a second detection sensitivity that is less sensitive than the first detection sensitivity.
