知器。[Scope of Claim for Utility Model Registration] 1. A heat ray detector that uses a pyroelectric element to mainly detect the human body, which comprises a pyroelectric element, a cylindrical body covering the pyroelectric element, and a filter on the front window. This device forms an element block and has a resin shielding body that prevents disturbance light from entering by covering the front surface of the cylindrical body at a certain interval, and this shielding body or the cylindrical body A heat ray detector characterized by having a mirror surface on the part of the body that is irradiated with ambient light. 2. The hot-wire type detector according to claim 1 of the utility model registration claim, in which chrome plating is applied to make a resinous material mirror-like.
