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 5 includes: a silicon substrate 5a which includes an ultrasonic transducer 5b for detecting an ultrasonic wave formed thereon and a through hole 5c passing through front and rear surfaces； an optical fiber 5d which oscillates a laser 7； a lens 5e which condenses the laser 7 and is arranged within the through hole 5c； a tubular housing 5f； a glass cover 5i which covers the lens 5e； and a resin 5g which fills a gap 10 between the through hole 5c and the lens 5e. Further, the silicon substrate 5a and the optical fiber 5d are fixed to a part of the housing 5f in the housing 5f.
