Abstract:
1. An infrared sensor comprising: a first substrate made of a thermoelectric conversion material; a second substrate arranged to be spaced apart from the first substrate such that a main surface of the second substrate faces a main surface of the first substrate; a plurality of posts arranged to connect the first substrate and the second substrate and support the first substrate and the second substrate while the first substrate and the second substrate are spaced apart from one another; and a sensing electrode arranged on at least one main surface of the first substrate, the sensing electrode sensing infrared rays incident on the first substrate; wherein an external terminal connection electrode arranged to be connected to an external circuit is arranged on a main surface of the second substrate opposite the main surface facing the first substrate, and the sensing electrode is electrically connected to the posts and the external terminal connection electrode.
