Abstract: A sphygmomanometer includes: a first fluid bag that is to be worn around a measurement site; first and second pulse wave sensors that are mounted on first fluid bag, and detect pulse waves of respective opposing areas of an artery running along measurement site; pressing parts that locally presses areas corresponding to first and second pulse wave sensors from an outer circumference side, opposite of an inner circumference side of first fluid bag where first and second pulse wave sensors are mounted. Blood pressure is calculated based on pulse transit time obtained from outputs from first and second pulse wave sensors, with first fluid bag in an unpressurized state and first and second pulse wave sensors being pressed by a pressing force of the pressing part. Blood pressure is calculated, for oscillometric blood pressure measurement, based on pressure within first fluid bag with first fluid bag in a pressurized state.

Abstract: An apparatus includes a first pulse wave sensor and a second pulse wave sensor that can be arranged in correspondence with respective measurement sites distant from each other. The first pulse wave sensor outputs a current signal having a first frequency to a measurement site and detects a voltage signal that represents pulse waves from the measurement site, based on a filter characteristic corresponding to the first frequency. The second pulse wave sensor outputs a current signal having a frequency different from the first frequency to a corresponding measurement site and detects a voltage signal representing pulse waves from the measurement site, based on a filter characteristic corresponding to a second frequency.

The support member (210) includes a length direction (L) corresponding to a circumferential direction of the device in an attached state to the measurement subject and a width direction (W) orthogonal to the length direction (L) and a thickness direction. The electrodes (41 to 46) are arranged side by side in the width direction (W). Low rigidity portions are provided between adjacent electrodes, the low rigidity portions having a lower rigidity than a rigidity of portions that overlap the electrodes in the thickness direction.
