PROBLEM TO BE SOLVED: To provide a biological measurement apparatus for measuring a location at which a light adsorber such as a tumor exists in the entire to-be-measured region. SOLUTION: The biological measurement apparatus 10 includes: a vessel 12 for holding an optical interface material 20; a light irradiation means for irradiating the to-be-measured region immersed in the optical interface material 20 with first and second lights having different wavelengths; a light detection means for detecting a diffusion light from the to-be-measured region; and a calculation/control section 14 for calculating internal information from an output signal of the light detection means. The wavelength λ1 of the first light is a wavelength at which an absorption coefficient of the to-be-measured region is substantially equal to an absorption coefficient of a medium. The wavelength λ2 of the second light is a wavelength at which the absorption coefficient of the to-be-measured region is larger than the absorption coefficient of the medium. The calculation/control section 14 calculates the internal information from the output signal related to the diffusion light of the first light, and calculates a boundary between the to-be-measured region and the optical interface material 20 from the output signal related to the diffusion light of the second light.
