Document Type and Number:
Japanese Patent JPH0529255
Kind Code:
B2
Abstract:
A polymer pyroelectric infrared sensor having an improved sensitivity and an improved heat resistance is formed by disposing a pyroelectric film having electrodes (3,4) for taking out a pyroelectric output on both sides so as to face a window (2) for introducing infrared rays. The pyroelectric film comprises a pyroelectric film of vinylidene fluoride copolymer having a crystallinity of 60 % or more and a relative dielectric constant of 10 or below at 25 DEG C and in a low frequency region of 0.1 - 10 Hz.
