  • an inflatable cuff which is adapted to be wound around a first portion of the subject to press said first portion with a pressing pressure;

    a pulse-wave detecting device which detects a pulse wave that is produced from an artery of said first portion of the subject pressed by the cuff with the pressing pressure and is transmitted to the cuff; and

    an arteriosclerosis judging means for judging, based on a change of the pulse wave caused by a change of the pressing pressure of the cuff, whether there is an arteriosclerotic lesion in a second portion of the subject that is located upstream of said first portion in a direction in which blood flows in the artery.
