Claim:
1. A photoacoustic wave measurement device comprising: a pulsed-light outputter that outputs a pulsed light; an arrangement spacer disposed between a pulsed-light output end of the pulsed-light outputter and a measurement object, the arrangement spacer being adapted to allow the pulsed light to pass therethrough; a photoacoustic wave detector that receives a photoacoustic wave generated by the measurement object by the pulsed light and that converts the photoacoustic wave into an electric signal, the photoacoustic wave measurement device being configured to receive the electric signal from a photoacoustic wave sensor in which the photoacoustic wave detector is farther from the measurement object than the pulsed-light output end; an electric signal recorder that receives and records the electric signal from the photoacoustic wave sensor; a noise timing estimator that estimates timing of occurrence of noise in the electric signal, from a thickness of the arrangement spacer; and a noise remover that removes the electric signal at the timing estimated, from contents recorded by the electric signal recorder.
