PROBLEM TO BE SOLVED: To provide an infrared imaging device capable of reducing the size and the mass of a horizontal scanner. SOLUTION: In this infrared imaging device, an infrared ray radiated from a temperature reference heat source is taken into an afocal lens system to thereby correct dispersion of infrared detection elements by using the infrared detection elements, in an ineffective scanning region set outside an effective scanning region on the afocal first image formation surface where an infrared image radiated from a measuring object body is imaged, and an infrared image imaged on the effective scanning region is displayed. The device is characterized by being equipped with a structure wherein the temperature reference heat source and a heat source introduction optical system for introducing the infrared ray radiated from the temperature reference heat source into the afocal lens system are fixed, and a reflecting mirror for taking the infrared ray radiated from the temperature reference heat source into the afocal lens system is fixed in a heat source introduction optical system lens-barrel constituting the heat source introduction optical system, and a shim is pinched between the heat source introduction optical system lens-barrel and a lens-barrel in the afocal lens system, and the heat source introduction optical system lens-barrel is screwed and fixed on the lens-barrel in the afocal lens system through a long-diameter hole provided on the heat source introduction optical system lens-barrel.
