A blood pressure measurement device includes a cuff, inflation/deflation unit, pressure detection unit, volume detection unit, and control unit. The control unit determines values of an arterial volume signal detected by the volume detection unit, changes a prescribed control target value from the determined value at a time of diastolic blood pressure to a vicinity of the value at the time of systolic blood pressure during a rise time, changes the prescribed control target value from the determined value at the time of systolic blood pressure to a vicinity of the value at the time of diastolic pressure during a fall time, and adjusts the pressure of the cuff by controlling the inflation/deflation unit such that the volume indicated by the arterial volume signal detected by the volume detection unit matches the prescribed control target value. Thus, by applying a control target value, blood pressure can be measured.
