In a photo-detection type ultrasonic receiving apparatus, the image quality of ultrasonic image has been enhanced by reducing multiple reflection of the ultrasonic wave. The ultrasonic receiving apparatus according to the present invention includes an ultrasonic detecting element (20) for modulating light on the basis of a received ultrasonic wave, a backing portion (13) directly or indirectly connected to the ultrasonic detecting element propagating the ultrasonic wave to be applied to the ultrasonic detecting element, the backing portion having optical transmissibility and guiding the light used for detecting ultrasonic wave, and a photoelectric conversion unit (15) that detects the light output from the ultrasonic detecting element. <IMAGE> |
