A photoacoustic apparatus obtains information on a specimen by receiving photoacoustic waves which are generated from the specimen resulting from light irradiated to the specimen. The apparatus includes a light source for irradiating light to the specimen, an acoustic wave receiver for receiving the photoacoustic waves, and a light reflection member for causing the light, which is radiated out of the specimen by optical diffusion thereof after having entered an interior of the specimen from the light source, to reenter the interior of the specimen, wherein the light reflection member allows elastic waves to pass therethrough. As a result, a photoacoustic apparatus and a probe are provided which can confine scattered light from the specimen into the specimen, and which can reliably prevent photoacoustic waves from being generated from a receiving element region of the probe by the scattered light.
A photoacoustic apparatus which obtains information on a subject by receiving photoacoustic waves generated from the subject resulting from the subject being irradiated with light, said apparatus comprising:
A probe which receives photoacoustic waves generated from a subject resulting from light with which the subject is irradiated and which has a receiving surface arranged in opposition to the subject, said probe comprising:
