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 P<SUB>K</SUB>(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 P<SUB>K</SUB>(t) is free of waveform distortion and accordingly enjoys high accuracy.
