PROBLEM TO BE SOLVED: To provide a technique to improve the measurement accuracy of a device which measures a pulse wave using a plurality of light sources.SOLUTION: A pulse wave measuring device comprises: a first light emitting unit which irradiates a pulse wave measurement site with light of a first wavelength; a first light receiving unit which receives the light of the first wavelength reflected off the measurement site and outputs a measurement signal based on an amount of received light; a second light emitting unit which irradiates the measurement site with light of a second wavelength; a second light receiving unit which receives the light of the second wavelength reflected off the measurement site and outputs a measurement signal based on an amount of received light, and which is arranged in a position where a line segment connecting the first light emitting unit and the first light receiving unit intersects a line segment connecting the second light emitting unit and the second light receiving unit when viewed from the measurement site; and a generation unit which generates a pulse wave signal indicative of the pulse wave on the basis of at least one of the first measurement signal output by the first light receiving unit and the second measurement signal output by the second light receiving unit.SELECTED DRAWING: Figure 1 |
