发明名称 INFRARED SENSOR DEVICE
摘要 <p>PROBLEM TO BE SOLVED: To provide an infrared sensor device which suppresses unnecessary infrared incidence from the outside of the viewing angle, and enables highly accurate infrared detection.SOLUTION: An infrared sensor device of the present invention includes: an infrared sensor part having a light reception part for outputting a signal in accordance with the incident infrared; and a structural body formed so as to encompass the infrared sensor part via an aperture, and for restricting the viewing angle of the infrared sensor part. The aperture includes a first aperture provided in an upper part of the structural body and contacting with the outside, and a second aperture communicating with the first aperture. The first aperture and the second aperture are set to have different aperture areas, respectively so that the infrared from the viewing angle is not incident upon the light reception part.</p>
