AbstractAn infrared radiation sensing device such as a pyroelectric effect device is mounted on one surface of an insulating substrate of alumina ceramic or the like. External connection leads are provided on the insulating substrate. A field effect transistor is provided on the other surface of the insulating substrate for amplifying the signal generated in the sensing device by incident infrared radiation. The apparatus is suitably encapsulated in a layer of resin.
