Abstract
An infrared sensor is provided with an infrared light receiver, a signal pathway, and a first member. The infrared light receiver has a structure in which at least two materials having different coefficients of thermal expansion are layered. The signal pathway includes a first signal pathway allowing passage of a driving signal to be applied to the infrared light receiver. The driving signal has a current value equal to or greater than a prescribed magnitude, and the infrared light receiver deforms in response to the application of the driving signal to the infrared light receiver, thereby at least a portion of the infrared light receiver contacting the first member.
