A manual pressurization electronic sphygmomanometer includes a specific component detection unit for detecting a synthetic wave of a manual fluctuation wave and a pressure pulse wave as a specific component from a cuff pressure signal obtained during pressurization a derivation processing unit for deriving a pressurization target value based on the detection result of the specific component detection unit and a display unit for notifying to urge pressurization up to the pressurization target value. The derivation processing unit calculates a pulse wave component based on the waveform before and after the specific component and the waveform of the specific component, and determines a value obtained by adding a predetermined value to the systolic blood pressure value estimated based on the amplitude of the pulse wave component as the pressurization target value.
