A biometrics sensor comprising a portion for sucking air, a molecular sieve portion for selectively passing or adsorbing specific gas contained in the air, a gas detecting section for detecting the concentration of gas passed through the molecular sieve or the remaining gas, and a data processing section for comparing the detection result with a prestored detection result, wherein the gas detecting section detects predetermined gas selectively, and the data processing section performs judgment or probabilistic judgment on an authentication object person by comparing the constitution ratio of gas for each authentication object person with a prestored constitution ratio. |
