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.
