摘要： A thermal infrared imaging device includes a diode, a power supply for supplying a constant power supply voltage to an anode of the diode through a first interconnection, a voltage setting circuit for setting a voltage across the diode, and a current read circuit which is connected to a cathode of the diode through a second interconnection and the voltage setting circuit, for reading a current of the diode. The voltage setting circuit controls a voltage of a connection point of the second interconnection and the voltage setting circuit to a voltage obtained by subtracting a voltage drop from a predetermined bias voltage. The voltage drop is generated by resistances of the first and second interconnections, and the diode current.
