Abstract
PURPOSE:To achieve a lower cost with a reduction in the number of parts, by employing a field effect transistor as a high resistance element and a load resistance connected in parallel to a pyroelectric detector. CONSTITUTION:An infrared detector includes insulation type field effect transistors T3 and T3 and a junction type field effect transistor T1 to be formed as one integrated element. When a pyroelectric type detector S is irradiated with infrared rays, a voltage is generated by a polarization effect of the pyroelectric detector S. The variation of the voltage thus generated is determined as that of a gate voltage of the junction type field effect type transistor T1 thereby taking out as output signal a change in current of the junction type field effect transistor T1 due to a change in the gate voltage from the field effect type transistor T3 composing a load resistance.
