A pulse discrimination device is configured to receive an electrical signal from a living body in which a functional pulse propagates at a predetermined time interval, and is configured to discriminate between the functional pulse and a noise pulse which are included in the electrical signal. The pulse discrimination device includes: a pulse detector configured to sequentially detect an electrical pulse included in the electrical signal based on variation in an intensity of the electrical signal received from the living body； and a pulse discrimination unit configured to determine whether the electrical pulse detected by the pulse detector is the functional pulse or the noise pulse based on a detection interval of the electrical pulse detected by the pulse detector and a pulse time predetermined based on the predetermined time interval.
