To provide an infrared imaging device capable of correcting a dispersion in responsibility and capable of correcting a dispersion in a dark current, as to the infrared imaging device of the present invention.

This infrared imaging device is provided with a concave mirror 22 with a reflecting face inserted opposedly to an infrared detector to block an incident optical path in a front face of the infrared detector combined with a plurality of infrared detecting elements, a temperature correcting part 23 inserted to block the incident optical path in the position same to that of the concave mirror 22, a driving means for inserting the concave mirror 22 and the temperature correcting part 23 into the front face of the infrared detector 3 for a prescribed time, and a signal processing circuit for correcting uniformly outputs from the respective front face of the infrared detector, under the condition where the incident optical path is blocked by the concave mirror 22 and the temperature correcting part 23, and is constituted to provide a spur gear in the rotational center of the concave mirror 22 and the temperature correcting part 23 arranged on the same base 21, and to arrange a counter weight 39 provided with a spur gear driven on one-to-one basis by the spur gear in the rotational center.
