A blood pressure measuring apparatus, which measures a blood pressure of a living body, includes: a cuff-pressure control unit which controls a cuff pressure of a cuff that presses a part of the living body； an oscillation signal detection unit which detects an oscillation signal from the cuff pressure； a blood pressure specification unit which specifies systolic and diastolic blood pressures as the blood pressure of the living body from the oscillation signal； and a blood pressure determination unit which determines whether systolic and diastolic blood pressures are appropriate or not. The cuff-pressure control unit controls the cuff pressure to be inflated to a first set value, the blood pressure specification unit specifies the systolic and diastolic blood pressures based on a change of an oscillation signal that is detected by the oscillation signal detection unit when the cuff pressure is inflated to the first set value, and when the blood pressure determination unit determines that both the systolic and diastolic blood pressures are appropriate, the cuff-pressure control unit ends the inflating of the cuff pressure to release the cuff pressure.
