Abstract
An infrared detection element is configured to prevent decreases in detection precision when a beam bends. The infrared detection element basically has a substrate structure, a light receiver configured and arranged to receive infrared rays and at least one beam having one end fixed to the substrate and another end fixed to the light receiver to support the light receiver above the substrate. At least one protuberance is provided on at least one of the substrate, the light receiver and the beam with the at least one protuberance being configured and arranged to limit direct contact between any two of the beam, the light receiver and the substrate structure during bending of the beam, except at the at least one protuberance.
