A biometric apparatus includes an instruction issuing unit configured to issue an instruction to an object person to be measured to execute a predetermined state a pulse sensor configured to measure a pulse rate in the predetermined state a consumed energy measuring unit configured to measure a consumed energy in the predetermined state and a biological data calculating unit configured to define a relational expression of the consumed energy with respect to a predetermined pulse rate of the object person to be measured on the basis of the pulse rate measured by the pulse sensor in the predetermined state and the consumed energy measured by the consumed energy measuring unit at the measured pulse rate, and calculate biological data of the object person to be measured on the basis of the defined relational expression.
