Abstract

A configuration is provided for firmly fixing a transmitting and receiving unit for IVUS and a transmitting and receiving unit for OCT in a probe of an imaging apparatus for diagnosis in which space saving is achieved. The probe includes a cylindrical housing in which an ultrasonic wave transmitting and receiving unit is arranged on a distal side and a light transmitting and receiving unit is arranged on a proximal side. The ultrasonic wave transmitting and receiving unit and the light transmitting and receiving unit being fixed to the cylindrical housing in a state where a base of the ultrasonic wave transmitting and receiving unit and a base portion of the ball lens of the light transmitting and receiving unit are embedded in an adhesive agent.
