PROBLEM TO BE SOLVED: To provide an endoscope tip device capable of generating and detecting a small circular polarized light which can be mounted on a tip portion of an endoscope. SOLUTION: An endoscope tip device including a circularly polarized light emitting diode for irradiation and a circularly polarized light emitting diode for detecting scattered light is provided. By equipping the endoscope tip device with a parabolic mirror, integration becomes possible.
