Abstract: An optical ultrasonic wave measuring apparatus includes an ultrasonic pulse output section, a light pulse output section, a reflected wave measuring section, an optoacoustic wave measuring section, an exceeding time point acquiring section, and a measurement result shifting section. The reflected wave measuring section measures, in correspondence to time, a reflected wave as a result of reflection of the ultrasonic pulse at a measuring target, which may be a skin surface. The optoacoustic wave measuring section measures, in correspondence to time, an optoacoustic wave generated by the light pulse at the measuring target. The exceeding time point acquiring section acquires an exceeding time point at which a measurement result of the reflected wave exceeds a predetermined threshold value. The measurement result shifting section shifts a measurement result of the optoacoustic wave by a first shift time toward the time point of output of the light pulse.
