    • A bolometer infrared detecting element has a thermal isolation structure in which a temperature detector comprising a bolometer thin film is held floating from a circuit substrate by beams. As infrared rays incident on the temperature detector or reflected by an infrared reflector are absorbed by a protective film and the bolometer thin film, the temperature of the bolometer thin film rises, and the temperature rise is detected as a change in resistance. When a high temperature object whose temperature is equal to or higher than a predetermined temperature or whose output voltage is equal to or higher than a value corresponding to the predetermined temperature is detected, a control temperature setter or a pulse bias setter performs control in such a way as to raise the temperature of a Peltier device stepwise or in a pulse form, or to increase the width of a pulse of pulse bias, or to increase the voltage value of the pulse. This makes it possible to raise the temperature of the infrared detecting element, thereby reducing an afterimage.
