Abstract
An apparatus for obtaining a pulse-wave-propagation-relating information of a living subject, including a bifurcate-portion determining device which determines a bifurcate portion of an artery of the subject that is present under a skin of the subject, a pulse-wave-detect-portion determining device for determining, based on the determined bifurcate portion of the artery, a pulse-wave-detect portion of the artery from which a pulse wave is detected, a reference-point determining device for determining a reference point on the pulse wave detected from the determined pulse-wave-detect portion of the artery, and a pulse-wave-propagation-relating-information obtaining device for obtaining the pulse-wave-propagation-relating information of the subject based on the determined reference point of the pulse wave.
