The present technology relates to a measurement device and a measurement method that can improve the accuracy of measurement of pulse waves and pulses.A body motion signal extracting unit extracts a body motion signal containing a component generated by body motion from a first band signal containing the components in a first frequency band of a first measurement signal acquired by illuminating a portion having a pulse with light of a predetermined wavelength. An arithmetic unit generates a pulse wave signal that is the differential signal between a second band signal and the body motion signal, the second band signal containing the components in a second frequency band of the first measurement signal. The present technology can be applied to devices that measure pulse waves and pulses, for example.
