Abstract
Abstract An infrared sensor including a substrate provided with a bridging part; a detecting part composed of an infrared temperature-sensitive film formed in the bridging part; an electrode pad formed of a laminate film and an etchant-resistant electrically conductive film electrically connected to the infrared temperature-sensitive film; a first lid covering the detecting part and the bridging part; and a second lid covering another surface of the substrate and tightly closing a cavity formed between the substrate and the bridging part.
