<p>PURPOSE:To enhance reliability with high sensitivity, by adhering a high-molecular pyroelectric film having metal layers vapor deposited to both surfaces thereof to a metal ring under tension and increasing the thickness of the vapor deposition film in the vicinity of the adhesion part of the metal ring as compared with that in the vicinity of the central part of said vapor deposition film. CONSTITUTION:Metal vapor deposition films 3, 4 are formed to a high-molecular pyroelectric film 1 comprising PVF2 and a metal ring 2 is adhered to the circular ridge 3a of the film 3 made thicker than the vicinity of the central part of said film 3 to constitute an infrared element. By this constitution, continuity resistance due to the fixation of the ring 2 by an adhesive can be reduced and the delamination of the ring 2 is prevented and sensitivity can be enhanced because the vapor deposition film in the vicinity of the central part thereof is thin.</p> |
