ABSTRACT:
A pyroelectric pellet made of a Z cut plane of lithium tantalate, for example, is fixed onto an electrically conductive supporting base made of copper, for example, by means of an adhesive agent layer. One embodiment of the adhesive agent layer interposed between the pyroelectric pellet and the electrically conductive supporting base comprises a mixture of an electrically conductive adhesive agent, such as a silver paste, admixed with heat insulating grains made of glass, ceramic, or the like, whereby thermal dissipation from the pyroelectric pellet to the electrically conductive supporting base is decreased. Another embodiment of the adhesive agent layer comprises an electrically conductive adhesive agent layer in which is embedded a thin sheet made of synthetic resin having apertures. The electrically conductive adhesive agent extends through the apertures of the sheet so as to fix the pyroelectric pellet to the electrically conductive supporting base.
