A pyroelectric-type IR receiving element comprises a pyroelectric substrate which is fixed to a supporting body at its support ends and at least one rectangular patch formed in the substrate. The patch is formed on its opposite surfaces with first and second electrodes which are overlapped to each other. The substrate has a U-shaped slit composed of a pair of side slits and a base slit connecting the side slits. The U-shaped slit surrounds continuously three sides of the patch, so that the patch is supported by the substrate in a cantilever fashion at a ...
[ What is claimed is:] [1.] A pyroelectric-type IR receiving element, comprising:a substrate made of a pyroelectric material which is fixed to a supporting body at its support ends; andat least one patch formed in said substrate to have a substantially rectangular shape, said patch being formed on its opposite surfaces with first and second electrodes which are overlapped with each other so as to develop a voltage difference between said first and second electrodes when one of said first and second electrodes receives an IR ray,wherein said substrate has...
