Abstract: An infrared sensor includes an infrared detecting device, a lens, a member, a gap and a spacer. The lens is disposed above the infrared detecting device. The member forms an external surface and includes a first opening having a maximum internal diameter. The gap is disposed between the member and the lens. The spacer is disposed between the member and the lens so as to form the gap, and that is directly contact with lens. The spacer has a circular inner periphery, in planar view, which has a larger internal diameter than the maximum internal diameter of the first opening of the member.

Abstract: An infrared sensor, which achieves a low manufacturing cost, or has high sensitivity, or in which an increase in heat capacity is reduced, is provided. The infrared sensor includes a first infrared absorbing portion, an infrared sensing portion for sensing infrared rays based on infrared rays absorbed by the first infrared absorbing portion, and a plurality of protrusions including metal and disposed apart from each other on a surface of the first infrared absorbing portion. Since an absorption rate of infrared rays is improved, sensitivity can be improved, or an increase in heat capacity can be reduced.
