PROBLEM TO BE SOLVED: To provide a contamination degree detector capable of detecting the degree of contamination of gas, and an air treatment device having the contamination degree detector. SOLUTION: This contamination degree detector comprises a gas-liquid contact section 10 (gas liquid contact means) for bringing gas into contact with liquid, an electrolysis section 14 (electrolysis means) as a producing means for producing active oxygen species in the liquid, a detecting means 16 for detecting absorbance of the active oxygen species in the liquid in contact with gas in the gas-liquid contact section 10, and a controlling means 70 for calculating the degree of contamination of the gas based on the absorbance of the active oxygen species in the liquid detected by the detecting means 16. The controlling means 70 calculates the degree of contamination of the gas based on the difference between the absorbance of the active oxygen species in the liquid before it comes into contact with the gas detected by a second contamination degree detecting section 52 of the detecting means 16 and the absorbance of the active oxygen species in the liquid after it comes into contact with the gas detected by a first contamination degree detecting section 51.
