Abstract
The light irradiation range of a probe for a photoacoustic measurement apparatus is increased. The probe for a photoacoustic measurement apparatus includes a light transmission unit that irradiates a subject with light, and a photoacoustic wave detectorthat detects a photoacoustic wave generated from the subject. The light transmission unit includes light propagation partfor propagating light, and a light transmission member. Further, the light transmission memberincludes an inner peripheral surfacethat is formed in the shape of a curved concave surface and an outer peripheral surfacethat has a radius of curvature larger than the radius of curvature of the inner peripheral surfaceand is formed in the shape of a curved convex surface. The outer peripheral surfaceis disposed so that the light L emitted from the light propagation partis incident on the inner peripheral surface
