ABSTRACT:
A small infrared sensor has a wide infrared light-receiving area (viewing angle), high electromagnetic shielding characteristics, and excellent electromagnetic-wave resistance characteristics. In the infrared sensor, supporting portions are disposed at four corners of a substantially rectangular opening in a package. The supporting portions support an optical filter, disposed so as to cover the opening, at positions that are lower than an upper end of an inner peripheral wall defining the opening. While the optical filter is supported by the supporting portions as a result of inserting a portion of a surface side of the optical filter facing the supporting portions into the opening, the optical filter is secured to the package. The optical filter and the package are joined and secured, and electrically connected to each other through a conductive adhesive.
