PURPOSE:To mass-produce pyroelectric elements of extremely thin thickness and high sensitivity and to obtain highly sensitive and inexpensive infrared ray detectors by producing said elements by a sheet method. CONSTITUTION:Pyroelectric elements are manufactured by a sheet method. For example, a coating film 5 which serves as a pyroelectric element is coated on a substrate 4 such as polyester film or the like by using the coating prepd. by mixing, for example, suitable ferrodielectric magnetic powder and a binder at prescribed amounts. After drying, an electric 6 consisting of an alloy of platinum and palladium type is coated by a printing method or the like. Next, it is affixed on a support table 8 by using an inorg. type adhesive material 7, and is fired at 1,000-1,200 deg.C, whereby the film 5 is calcined and sintered; at the same time, the material 7 is cured and the substrate 4 is burned out. Thence, it is cut to a suitable size, whereby an infrared ray detector is provided. According to the above-mentioned method, the element of small thickness in the element part hence high sensitivity is manufactured inexpensively in good yields. |
