A blood pressure measurement unit measures the blood pressure and a CPU accordingly stores, in a blood pressure storage unit, measurement data as well as time information regarding the time at which the blood pressure is measured. The CPU calculates, as representative measurement data, the average of a plurality of measurement data stored in the blood pressure storage unit and correlated with the time information indicating a time in the range between nine weeks ago and ten weeks ago, correlates the representative measurement data with time information representing the corresponding week and stores the data with the time information in the blood pressure storage unit. At this time, the CPU deletes from the blood pressure storage unit those measurement data based on which the representative measurement data is calculated.

Every pulse wave, a constant volume control unit performs servo control while updating a servo gain such that a difference between an arterial volume shown by an arterial volume signal that is detected by an arterial volume detection circuit and a control target value of the servo control is less than a control deviation at which a rate of change of the arterial volume relative to a change in cuff pressure is deemed to be constant. Because the control deviation is the difference between the arterial volume shown by the arterial volume signal and the control target value, a blood pressure decision unit decides, as a blood pressure, the cuff pressure sequentially detected in a period during which servo control is performed, by correcting the cuff pressure using the control deviation and the rate of change deemed to be constant.
