Abstract
An object of the invention is to reduce the size of a probe for a photoacoustic measurement device. A light guideis arranged such that one of a two side surfacesis closer to a probe axis C which faces a subject than the other side surface and a light emission end surfaceis closer to the probe axis C than a light incident end surfacewhen the probe is used. When a refractive index of the light guidewith respect to the light is n1 and a refractive index of a medium around the light guide with respect to the light during photoacoustic measurement is n2 (n2<n1), the light emission end surfaceis obliquely formed such that an angle α[°] (where 90°−arcsin(n2/n1)<α<90°) is formed between the light emission end surfaceand the side surface
