PROBLEM TO BE SOLVED: To provide a photoacoustic probe capable of keeping power consumption low, stably irradiating an analyte with light having high light energy, and detecting an accurate photoacoustic wave.SOLUTION: A photoacoustic probe 10 has a light source part 13, and an acoustic wave detection part 14 arranged adjacently to the light source part 13, for detecting an acoustic wave generated when light from the light source part is absorbed by an analyte inner part. The acoustic wave detection part 14 is connected to the light source part 13 tiltably in the state where the light source part 13 is pressed against an analyte Bd.SELECTED DRAWING: Figure 4COPYRIGHT: (C)2016,JPO&INPIT【課題】消費電力を低く抑えるとともに、高い光エネルギの光を安定的に被検体に照射し、正確な光音響波を検出できる光音響探触子を提供する。【解決手段】光源部13と、光源部13と隣接して配置されるとともに前記光源部からの光が前記被検体内部で吸収されたとき発生する音響波を検出する音響波検出部14とを有し、音響波検出部14が、光源部13を被検体Bdに押し付けている状態で傾斜可能なように光源部13に連結されている光音響探触子10。【選択図】図4
