PROBLEM TO BE SOLVED: To provide an optical imaging probe for obtaining stable observation images.SOLUTION: The optical imaging probe includes: a rotary drive source having a rotor 2 rotating around a central axis rotation support members 3, 4 for supporting the rotor 2 on both sides in the axis direction of the rotor freely rotatably an optical fiber 5 inserted in the axis direction with respect to the rotor 2 and the rotation supporting members 3, 4 and an optical path conversion element 8 supported on one end side of the rotor 2 so as to convert the direction of light guided by the optical fiber 5 into an almost crossing direction with respect to the axis direction.
