SENSOR UNIT, BIOLOGICAL INFORMATION DETECTION APPARATUS, ELECTRONIC DEVICE, AND BIOLOGICAL INFORMATION DETECTION METHOD

摘要

Provided are a sensor unit for acquiring highly precise pulse wave information on the basis of a plurality of signals having different characteristics, a biological information detection apparatus, an electronic device, and a biological information detection method. A sensor unit 40 includes a first light-emitting part 150 for emitting light to a subject, a second light-emitting part 151 for emitting light to the subject, and a light-receiving part 140 for receiving light from the subject, the expression H1 H2 being satisfied, where H1 is the height of a position or region of contact with the subject in a position or region corresponding to the first light-emitting part 150, and H2 is the height of a position or region of contact with the subject in a position or region corresponding to the second light-emitting part 151.
