This optoacoustic imaging device is provided with: a light source part for irradiating an object to be inspected with light； an ultrasonic vibrator for detecting an acoustic wave generated from a subject to be detected in the object to be inspected which has absorbed the light emitted from the light source part； and a detecting part disposed in a probe body and including an acoustic lens disposed closer to the tip side of the probe body than the ultrasonic vibrator, wherein the acoustic lens is configured to have a light absorbance of 1-30% and a light reflectance of less than 85% with respect to light which has a wavelength band of 650-1000 nm and is emitted from the light source part.
