Abstract: High blood pressure measurement accuracy can be achieved with a blood pressure monitor employing a double cuff structure. A blood pressure monitor of the present invention includes a pressing member that includes a pressure cuff having a bag shape capable of containing fluid and generates a pressing force toward a measurement site of a subject when the pressing member is wound around the measurement site and the pressure cuff is inflated, and a controller that controls an operation of the adjuster such that the fluid is contained in the sensing cuff in an amount corresponding to biometric information about the subject and the pressure cuff is inflated or inflated and deflated in this state when performing a blood pressure measurement, and calculates a blood pressure value of the subject based on an output from the pressure sensor.
