Abstract
An infrared camera includes a lens unit including a lens and a lens barrel, 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, thus reducing the influence of infrared light coming without passing through the lens on capturing of an image.
