PROBLEM TO BE SOLVED: To provide a technique capable of enhancing accuracy of measurement in a device performing the measurement of a pulse wave by using a plurality of light sources.SOLUTION: A pulse wave measurement device comprises: a first light-emitting section irradiating light of a first wavelength to a measurement site where a pulse wave is measured a first light-receiving section receiving light generated by the light of the first wavelength being reflected on the measurement site, and outputting a measurement signal based on a light receiving amount a second light-emitting section irradiating light of a second wavelength to the measurement site a second light-receiving section receiving light generated by the light of the second wavelength being reflected on the measurement site, and outputting a measurement signal based on a light receiving amount, the second light-receiving section provided at a position where, as viewed from the measurement site, a line segment connecting the first light-emitting section and the first light-receiving section intersects with a line segment connecting the second light-emitting section and the second light-receiving section and a generation section generating a pulse wave signal indicating the pulse wave on the basis of at least any one of a first measurement signal output by the first light-receiving section and a second measurement signal output by the second light-receiving section.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT
