Abstract: A precision infrared detection device is provided, which is capable of measuring a wide range of temperature having a simple constitution, reduces the influence due to the dispersion among the operating points, and enables the cost down. The infrared detection device includes: reference voltage generation means 101 for generating a specific reference voltage; ambient temperature compensation means 102, to which a reference voltage from the reference voltage generation means 101 is applied, for outputting a signal for compensating the ambient temperature; first amplification means 103 for amplifying the signal outputted from the ambient temperature compensation means 102; infrared detection means 104, to which a signal outputted from the first amplification means 103 is applied, for converting infrared radiation energy into an electric signal; and second amplification means 105 for amplifying a signal outputted from the infrared detection means 104.
