A pyroelectric IR-sensor in which a pyroelectric light receiving element is mounted on a MID substrate or a ceramic substrate having a thermal conductivity less than 0.02 cal/cm.sec..degree.C. Both ends of the pyroelectric light receiving element are supported by the substrate, with the central portion of the pyroelectric light receiving element being spaced from the substrate. Chip parts are mounted on the substrate.

Pyroelectric IR-sensor

A pyroelectric IR-sensor in which a pyroelectric light receiving element is mounted on a MID substrate or a ceramic substrate of which thermal conductivity is less than 0.02 cal/cm.sec..degree. C. in a manner that both end portions of the pyroelectric light receiving element are supported by the substrate with the central portion of the pyloelectric light receiving element being spaced from the substrate, and chip parts are further mounted on the substrate.
