A life expectancy estimation apparatus for estimating a predicted value of life expectancy by pulse information of a biological body. The life expectancy estimation apparatus includes an obtaining unit operable to obtain the pulse information; a storage for storing a record of pulse information of a biological body including a plurality of entries of pulse beat rates of the biological body over a period of time; and a calculation unit operable to calculate an estimated value of life expectancy from the number of remaining pulse beats and the pulse beat rates, the number of the remaining pulse beats being estimated by subtracting the number of total pulse beats in the past estimated from the record of the pulse information from the predetermined estimated value of total pulse beats in a whole life time of the biological body.
