Abstract: An ultrasound imaging probe capable of securing an assembly accuracy of and improving a resolution performance of an obtained image is provided. A photoacoustic catheter includes: a silicon substrate which includes an ultrasonic transducer for detecting an ultrasonic wave formed thereon and a through hole passing through front and rear surfaces; an optical fiber which oscillates a laser; a lens which condenses the laser and is arranged within the through hole; a tubular housing; a glass cover which covers the lens; and a resin which fills a gap between the through hole and the lens. Further, the silicon substrate and the optical fiber are fixed to a part of the housing in the housing.
