A subject evaluation value measuring apparatus 10, functioning as a cuff volumetric pulse wave obtaining apparatus, includes a pulse wave determining device (i.e., a cuff volumetric pulse wave determining device) 52 that determines, using an inverse transfer function 1H(f), stored in a ROM (i.e., an inverse transfer function memory) 42, that corresponds to a pre-determined transfer function H(f) between input, i.e., pressure pulsation produced in a cuff 20, and output, i.e., pressure pulsation detected by a pressure sensor 24, a no-delay cuff volumetric pulse wave PK(t) having substantially no delay of transmission, based on an actual cuff pulse wave signal SM outputted by the pressure sensor 24. The thus determined cuff volumetric pulse wave PK(t) is free of waveform distortion and accordingly enjoys high accuracy.
