Abstract

Provided is a pulse wave detection device with which it is possible to improve the detection accuracy of pulse waves, and a biometric information measurement device equipped with same. This pulse wavedetection unit 100 is equipped with: a sensor unit 6 having two element rows 60, 70, each comprising pressure detection elements arranged in direction B, arranged in a direction A perpendicular to direction B, and an air bag 2 that presses sensor unit 6 against the surface of the body with direction B intersecting with the direction in which an artery in the body extends beneath the skin. The arrangement interval (distance L1) of the two element rows 60, 70 in direction A is 5 mm to 15 mm.

Description

technical field [0001] The present invention relates to a pulse wave detection device and a biological information measurement device. Background technique [0002] There is known a biological information measuring device capable of measuring pulse, heart rate, or blood pressure using information detected by the pressure sensor in a state where the pressure sensor is brought into contact with the body surface of a living body part through which arteries such as the radial artery of the wrist pass. and other biological information (see Patent Document 1). [0003] Patent Document 1 discloses a biological information measurement device having a driving unit that surrounds a pressure sensor having a plurality of element rows composed of a plurality of pressure detection elements in a direction that is in the same direction as the arrangement direction of the plurality of element rows. The axis extending in the orthogonal direction (orthogonal to the artery) is rotated. This b...
