Abstract
A biological information measurement device includes: a scattering rate calculating unit configured to calculate a scattering rate of light at an interface between a medium present in a biological object or in a specimen and a particle included in the medium based on received-light intensity of light irradiated onto the biological object or onto the specimen and received via the biological object or via the specimen; and a concentration index calculating unit configured to calculate, based on a correlation between the scattering rate of the light at the interface and a concentration index corresponding to concentration of a target substance that is different from the particle included in the medium, the concentration index corresponding to the scattering rate of the light calculated by the scattering rate calculating unit.
