The invention provides a photoacoustic measurement device that can confirm the position of a puncture needle in a photoacoustic image even in the case where the puncture needle is stuck to a deep position from the surface of a subject. Further, the invention provides a puncture needle that is used for the photoacoustic image generating device. The puncture needle 14 is a hollow needle that has an opening formed at a tip thereof. The puncture needle 14 includes a puncture needle body 31 and a light guide 32. The light guide 32 extends in a longitudinal direction of the puncture needle body. The light guide 32 emits light at least in part to the puncture needle body 31 while guiding light emitted from a light source toward the tip of the puncture needle body.
