Infrared camera

An infrared camera comprising:

• a lens unit including a lens that focuses infrared light and a lens barrel that holds the lens;
• a heater that is provided at the lens unit and heats the lens;
• an infrared image sensor that captures an image using infrared light focused by the lens;
• a chassis that is fixed to an external surface side of the lens barrel while being thermally insulated from the lens unit and contains the infrared image sensor;
• and
• a light-blocking member that is located between the lens barrel and the infrared image sensor inside the chassis as viewed in a direction of an optical axis of the lens and blocks infrared light radiated toward the infrared image sensor and coming without passing through the lens,
• wherein the light-blocking member which is fixed to an internal surface side of the chassis, is in a state of being thermally insulated from the heater.
