A biological information measurement apparatus includes an irradiation unit configured to irradiate a living body with light or sound waves as measurement waves； a detection unit configured to detect the measurement waves having passed through the inside of the living body； and a computational unit configured to obtain a change over time in blood flow rate and a change over time in blood vessel cross-sectional area based on a detection result from the detection unit, and to obtain a pulse wave propagation velocity from the change over time in blood flow rate or the change over time in blood vessel cross-sectional area.
