PURPOSE:To increase the output voltage for an infrared-ray detecting element, by installing an infrared-ray reflecting plate and at the same time pressing a metallic frame to which a high-molecular pyroelectric film is adhered to a spacer by means of a ring-shaped waveform spring to secure an assured connection. CONSTITUTION:For an infraredray detecting element using a high-molecular pyroelectric film, the polyfluoride vinylidene film is used for the high-molecular pyroelectric film 7 install an infraredray reflecting plate 11. In addition, the metallic frame 6 to which the film 7 is adhered is pressed to the spacer 4 by a ring-shaped waveform panel 8 to secure an assured connection. Thus the infraredrays are irradiated to the film 7 via the hole 2 of the metallic cap 1, and as a result, the electric charge is caused to the film 7. At the same time, the electric charge is also caused to the film 7 by the infraredrays transmitted through the film 7 and reflected by the reflecting plate 11. As a result, a large amount of output voltage between the electrodes on both surfaces of film 7 to ensure a high-sensitivity detection of the infrared-rays. |
