A pulse wave analyzing apparatus including a cuff 12 for detecting a pulse wave from a living subject, a pressure sensor 16 for converting the pulse wave detected by the cuff 12 , into an electric signal, i.e., a pulse wave signal SM, a plurality of band-pass filters 62 (BPF( 1 ), BPF( 2 ), . . . , BPF(n)) that have respective low-side cuff-off frequency bands differing from each other and each receive the pulse wave signal SM, a provisional rising point determining device 64 for determining respective times PS of respective provisional rising points of respective pulse waves represented by respective secondary pulse wave signals SM 2 that have passed through the band-pass filters 62 , and a proper rising point determining device 66 for comparing the respective times PS of respective provisional rising points with each other and thereby determining a time AS of a proper rising point based on the respective times PS of respective provisional rising points.
