According to such arrangements 201 and 202, photoacoustic signals in the stripe inspection areas of the sample can be detected simultaneously in parallel. Since photoacoustic signals in the stripe inspection areas of the sample can be detected simultaneously in parallel, two-dimensional surface and internal information of the sample can be detected at a high rate. Furthermore, since a photoacoustic signal subjected to correction of reflectivity distribution, irregularities distribution on the surface of the sample and fluctuation of optical path can be detected, stabilized high sensitivity detection can be ensured.
