Infrared sensor having no package can
First Claim
1. An infrared sensor comprising:
- an optical filter plate that allows selected infrared rays to pass therethrough;
an infrared-detecting plate having a detector element that detects the infrared rays passed through the optical filter plate; and
a supporting member, disposed between the optical filter plate and the infrared-detecting plate, for mechanically connecting the optical filter plate and the infrared-detecting plate and for forming a predetermined gap between both plates, the supporting member being positioned to surround the detector element on the infrared-detecting plate.

Abstract
An infrared sensor is composed of an optical filter plate, an infrared-detecting plate and a supporting member positioned between both plates. A detecting element for detecting infrared rays passing through the optical filter plate is formed on a front surface of the infrared-detecting plate facing the optical filter plate. The supporting member is positioned to surround the detector element on the infrared-detecting plate to firmly connect both plates and to form a predetermined gap between both plates. The supporting member may be composed of a number of discrete dots positioned to surround the detector element or of a continuous ring surrounding the detector element.
