A photoacoustic wave measurement device includes a pulsed-light outputter, an arrangement member and a photoacoustic wave detector. The pulsed-light outputter outputs a pulsed light. The arrangement member is disposed between a pulsed-light output end of the pulsed-light outputter and a measurement object, the arrangement member being adapted to allow the pulsed light to pass therethrough. The photoacoustic wave detector receives a photoacoustic wave generated by the measurement object by the pulsed light and converts the photoacoustic wave into an electric signal. The photoacoustic wave detector is farther from the measurement object than the pulsed-light output end. The arrangement member has such a sufficient thickness that noise to be detected by the photoacoustic wave detector after a start time of detection of the photoacoustic wave starts to be detected after an end time of the detection of the photoacoustic wave.
