Abstract

A heater includes a substrate, a first heating element and a second heating element disposed on a first surface of the substrate, a temperature detection element, and a conductor. The temperature detection element is disposed on a second surface of the substrate opposite the first surface of the substrate. The conductor is disposed on the second surface and connected to the temperature detection element. The first heating element has a first distance from the temperature detection element in a lateral direction of the substrate orthogonal to a longitudinal direction of the substrate, and the second heating element has a second distance that is greater than the first distance from the temperature detection element in the lateral direction. As viewed in a thickness direction of the substrate orthogonal to the lateral direction and the longitudinal direction of the substrate, the conductor overlaps the first heating element and the second heating element.
