A manually pressurized electronic sphygmomanometer is provided with a specific component detecting unit (104) for detecting, as a specific component, a synthetic wave of a manual fluctuation wave and a pressure pulse wave from a cuff pressure signal obtained during pressurization, a derivation processing unit (106) for deriving the pressurization target value on the basis of the result of the detection by the specific component detecting unit (104), and a display unit (40) for giving notice for prompting the pressurization up to the pressurization target value. The derivation processing unit (106) calculates the pulse wave component, for example, on the basis of the waveforms before and after the specific component and the waveform of the specific component, and determines, as the pressurization target value, the value obtained by adding a predetermined value to the maximum blood-pressure value estimated on the basis of the amplitude of the pulse wave component.
