Abstract: To provide an automatic blood pressure measurement device that can precisely decide a minimum blood pressure of a living body by using information of a reflected wave included in a pulse wave obtained from an intermediate expansion bag.SOLUTION: A minimum blood pressure DBP of a living body is determined by a minimum blood pressure determination unit 90, based on a compression pressure PC of a compression band when a reflected wave reflected from a point where an arterial cross section is varied to the upstream side and superposed on an intermediate pulse wave SM2 is attenuated by a predetermined amount or more under the downstream end of a downstream side expansion bag, in the process of dropping from the boosting target pressure value PCM where the compression pressure PC of the compression band is sufficiently higher than the maximum blood pressure SBP of the living body. The minimum blood pressure DBP can stably be determined, based on the attenuation of the reflected wave superposed on the intermediate pulse wave SM2 in the vicinity of the minimum blood pressure DBP with the variation of the compression pressure PC, and thereby the accuracy of determining the minimum blood pressure DBP of the living body can be increased.SELECTED DRAWING: Figure 5
