Abstract
A pressurizing unit applies pressure around a measurement site of a measurement subject so as to suppress blood flow at the measurement site during a set pressurizing time. While the pressurizing unit is applying pressure around the measurement site, a detection unit detects a photoacoustic signal generated at the measurement site irradiated with a light beam. The detection unit detects a photoacoustic signal when a preset time has elapsed after the pressurizing unit started to apply pressure around the measurement site.
