PROBLEM TO BE SOLVED: To emit both of an excitation light and a visible light by a single light source.
SOLUTION: An ultraviolet light emitted from the light source 15 enters a first branch light guide section 31 through a light branch device 22. The ultraviolet light is diffused inside the first branch light guide section 31, transmits through a grating 33 and is guided to an outgoing end 31B. At the outgoing end 31B, the ultraviolet light is converted into the visible light by a light wavelength conversion section 24 and emits from the distal end 12A of an insertion section 12. When the first branch light guide section 31 is longitudinally extended by an external force application section 27, the grating 33 changes its transmission characteristics to reflect the ultraviolet light from the light source 15. The reflected ultraviolet light reenters the light branch device 22. The reentered ultraviolet light is reflected by the light branch device 22, enters a second branch light guide section 32 and goes out from the distal end 12A of the insertion section 12 as the excitation light.
