An infrared detector having pixels which convert the infrared ray into an electric signal and are arranged to form a matrix. An infrared detecting unit is placed in a vessel having a shielding member for preventing the incident infrared radiated from the target object from being inputted to reference pixels. Only the infrared ray radiated from the shielding member is inputted to the reference pixels. The amount of infrared ray received by the reference pixels is supposed to equal the amount of infrared ray radiated from the inner wall of the vessel. The pixels other than the reference pixels receive the infrared ray both from the target object and the inner wall of the vessel. The circuit for reading out the electric signal generated by the pixels reads out the electric signal from the pixels using the electric signal from the reference pixels as a reference point.
