Abstract: An automatic blood pressure measuring apparatus includes: a compression band wrapped around a compressed site of a living body, the automatic blood pressure measuring apparatus sequentially extracting a pulse wave that is pressure oscillation in the compression band in a process of changing a compression pressure value of the compression band to determine a blood pressure value of the living body based on a change in the pulse wave, the compression band having a plurality of expansion bags having independent air chambers aligned in a width direction to respectively compress the compressed site of the living body, the automatic blood pressure measuring apparatus sequentially calculating an amplitude ratio of an amplitude value of a pulse wave from a predetermined expansion bag positioned on a downstream side of an upstream expansion bag positioned on an upstream side of an artery in the compressed site out of the expansion bags.
