To provide a light emitting device with rich color reproducing property with little variation in color tone, and also to provide the light emitting device of high performance and long service life obtaining high light emitting efficiency by preventing deterioration of members comprising the light emitting device.
The light emitting device is constituted of: an excitation light source which radiates excitation light; a light guide which is flexibly extended along a longitudinal direction for guiding the excitation light radiated from the excitation light source; and a wavelength converting member which absorbs and converts the wavelength of the excitation light radiated from the excitation light source through the light guide and releases light with a predetermined wavelength band. The light guide is provided with an end surface with a greater area than a cross sectional area orthogonally crossing in the longitudinal direction on the side on the radiated excitation light and is supported by a light guide tip member and the light guide and at least a part of the light guide tip member are covered by the wavelength converting member.
