PROBLEM TO BE SOLVED: To provide a biometric device and a biometric method which can determine whether or not a human body contacting with an electrode is in a state suitable for the measurement (an adhered state), namely in a state of being wet with water.SOLUTION: A biometric device includes: biological information measuring means which includes a cluster of electrodes used for measurement of biological impedance of a user contact impedance measurement means which, by using two or more electrodes, measures contact impedance caused between the user and the electrode when the user is contacting with the electrode and determination means which determines whether or not the contact impedance measured by the contact impedance measurement means is in a first prescribed range.COPYRIGHT: (C)2015,JPO&INPIT【課題】電極と接触する人体が、測定に適した状態(密着した状態)、即ち水で濡れているか否かの状態を判別できる生体測定装置及び生体測定方法を提供する。【解決手段】使用者の生体インピーダンスの測定に用いる電極群を備えた生体情報測定手段と、2つ以上の電極を用いて、使用者が電極に接触したときに使用者と電極との間に生ずる接触インピーダンスを測定する接触インピーダンス測定手段と、接触インピーダンス測定手段が測定した接触インピーダンスが、第1所定範囲内にあるか否かの判別をする判別手段と、を備える。【選択図】図2
