An apparatus (10, 80) for examining arteriosclerosis of a living subject, comprising a pulse-wave detecting device (40, 42, 44, 46) which detects a pulse wave from a first portion of the subject; a stenosis-related-information obtaining means (62, 84) for obtaining, based on a shape of the pulse wave detected by the pulse-wave detecting device, stenosis-related information that changes in relation with stenosis of an artery of a second portion of the subject that is located upstream of the first portion of the subject in a direction in which blood flows in the artery; and a stenosis judging means (68, 86) for making, based on the stenosis-related information obtained by the stenosis-related-information obtaining means, a judgment about the stenosis of the artery of the second portion of the subject.
