To obtain a biological state determination device capable of facilitating acquisition of heartbeat information of a subject and capable of reducing an influence of a variation of the heartbeat information among individuals.SOLUTION: A biological state determination device includes: a base heart rate acquisition part for acquiring a base heart rate of a subject; a heart rate acquisition part for acquiring a heart rate of the subject; and a determination part for determining a state of the subject, using the base heart rate and the heart rate. The heart rate corresponds to the number of crests in an electrocardiographic waveform, meanwhile, the number of crests is matched with the number of contraction times of the heart. Therefore, acquiring the heart rate through acquisition of heartbeat information of the subject is easier to acquire a correct numerical value of the heart rate than through acquisition of a heartbeat interval. Also, the base heart rate is a heart rate during deep sleep specific to each individual, and has a correlation to a heart rate at a normal time. An influence of a variation of heartbeat information among individuals is reduced by determining a state of the subject on the basis of the correlation.SELECTED DRAWING: Figure 4

    【課題】被験者の心拍情報の取得が容易になり且つ心拍情報の個人毎のばらつきの影響が少なくなる生体状態判定装置を得る。【解決手段】生体状態判定装置は、被験者の基底心拍数を取得する基底心拍数取得部と、前記被験者の心拍数を取得する心拍数取得部と、前記基底心拍数と前記心拍数とを用いて前記被験者の状態を判定する判定部と、を備える。心拍数は、心電図の波形における山の数に相当するが、この山の数と心臓の収縮の回数とは一致する。このため、被験者の心拍情報として心拍数を取得する場合、心拍間隔を取得する場合と比較して、正しい数値を取得し易い。また、基底心拍数は、個人特有の深睡眠時の心拍数であり、平常時の心拍数と相関がある。この相関関係に基づいて被験者の状態を判定することにより、心拍情報の個人毎のばらつきの影響が少なくなる。【選択図】図4
