An imaging probe is disclosed for diagnosis, which includes an imaging core having a drive shaft internally provided with an optical fiber and a signal line. The imaging probe for diagnosis includes an optical transceiver that is disposed in one end of the optical fiber, and an ultrasound transceiver that is joined to the signal line. The optical transceiver is arranged on a distal side of the imaging core from the ultrasound transceiver. An emitting direction of an ultrasound wave emitted from the ultrasound transceiver and an emitting direction of light emitted from the optical transceiver are substantially parallel to each other, and are directions, which further tilt to a proximal end of the drive shaft than a direction orthogonal to the drive shaft.
