PROBLEM TO BE SOLVED: To provide an infrared imaging apparatus capable of obtaining excellent sensitivity data for correction without being affected by the surrounding environment, the infrared imaging apparatus including an image sensor in which pixels each of which comprising an infrared sensor element capable of obtaining an electric output signal in accordance with the quantity of incident infrared rays are disposed in a matrix shape. SOLUTION: The infrared imaging apparatus 1 includes: an image sensor 3 including a plurality of pixels; a reference heat source 7 which makes the fixed quantity of infrared rays incident to the plurality of pixels when correcting the sensitivity dispersion of the plurality of pixels; and an integration time adjusting mechanism 9 for adjusting an integration time during the correction. The integration time adjusting mechanism 9 includes: an integration time adjustment pixel group 11 which outputs an integration voltage corresponding to the quantity of infrared rays incident from the reference heat source 7; a voltage comparator 13 for comparing the integration voltage from the integration time adjustment pixel group 11 with a reference voltage; and an integration time setting section 15 for setting the integration time during the correction based on a result of comparison in the voltage comparator 13.
