Abstract
A sensor array having a plurality of pressure sensors arranged on a measurement surface, a pressurization portion for pressing the sensor array laid across an artery of a living body, a sensor signal selection portion for selecting a pressure signal among pressure signals from the plurality of pressure sensors, a filter portion having a cutoff frequency variable corresponding to an instruction, and a filter control portion for providing an instruction to vary a value of the cutoff frequency are included. The filter control portion switches the cutoff frequency in a situation wherein a plurality of pressure signals respectively obtained from the plurality of pressure sensors are successively switched and output by the sensor signal selection portion to specify the pressure sensor for pulse wave detection, and in a situation wherein the pulse wave is detected from the specified pressure sensor.
