<P>PROBLEM TO BE SOLVED: To provide a highly sensitive thermal infrared detection element that can suppress a negative feedback effect due to a wiring resistance. Ž<P>SOLUTION: In this thermal infrared detection element, a voltage setting circuit (1102) for setting a voltage applied to both ends of an infrared detection diode (101) is serially connected to the diode (101). A dummy diode array (A2) including dummy diodes each not having an infrared absorption structure and/or a heat insulation structure is provided independent from a pixel array (A1). The voltage setting circuit (1102) controls a cathode voltage of the diode (101) so as to make it to be a voltage obtained by subtracting a drop voltage generated by a wiring resistance, a signal line resistance and a drive line resistance and a diode current "If" from a predetermined bias voltage. Degradation of sensitivity by a negative feedback effect due to a wiring resistance of the pixel array (A1) is canceled by the dummy diode array. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
