1. An arterial-wall stiffness evaluation system comprising:

  • a cuff to be attached to a part of a living body;

    a pressure sensor for detecting pressure in the cuff;

    cuff-pressure control means for controlling the pressure in the cuff to be increased or decreased to a predetermined value, based on a value detected by the pressure sensor; and

    data processing means for calculating, based on pulse waves detected by the pressure sensor, pulse-wave amplitudes of cuff-pressure pulse waves and blood-pressure pulse waves, and for evaluating arterial-wall stiffness based on the pulse-wave amplitudes thus calculated.
