PROBLEM TO BE SOLVED: To provide a photoacoustic apparatus and a probe which can confine scattered light from a specimen into the specimen while reliably preventing photoacoustic waves being generated from a receiving element region of the probe by the scattered light.SOLUTION: The photoacoustic apparatus obtains information on the specimen by receiving photoacoustic waves 8 which are generated from the specimen resulting from light irradiated to the specimen. The apparatus includes a light source 3 for irradiating light to the specimen and an acoustic wave receiver having a receiving surface opposing to the specimen, a light reflection member 6 and a receiving element 9 for receiving the photoacoustic waves provided in order from the specimen side in the receiving surface. The light reflection member adheres to the receiving surface.COPYRIGHT: (C)2012,JPO&INPIT【課題】被検体からの散乱光を被検体内に閉じ込めることが可能で、且つ該散乱光によって探触子の受信素子領域から光音響波が発生するのを確実に抑制することが可能となる光音響装置、および探触子を提供する。【解決手段】被検体に照射された光に起因して該被検体から発生する光音響波8を受信して、被検体の情報を得る光音響装置であって、前記被検体に光を照射する光源3と、前記被検体に対向する受信面を有し、該受信面に前記被検体側から順に設けられた光反射部材6及び前記光音響波を受信する受信素子9を備える音響波受信器と、を有し、前記光反射部材は前記受信面に接着されている構成とする。【選択図】図1
