PROBLEM TO BE SOLVED: To provide a linear light emitting body which can be easily attached to an object to be attached with the linear light emitting body, is excellent in light emitting performance in use and can be efficiently manufactured.SOLUTION: For a core layer 1, an acrylic resin of a refractive index of 1.45 to 1.60 is selected and for a clad layer 2, a fluororesin of a refractive index of 1.35 to 1.45 is selected so that a difference in refractive index between the core layer 1 and the clad layer 2 becomes 0.01 to 0.15, whereas the clad layer 2 is formed in such a way that a maximum thickness is 0.05 to 1.0 mm, a total ray transmittance of visible light is 60% or more, and a haze value becomes 20% to 90%. Moreover, for the clad layer 2, a fluororesin where a functional group for imparting adhesiveness to a prescribed non-fluororesin is introduced is used, and for a light reflection layer 3, a non-fluororesin having adhesiveness with the fluororesin of the clad layer 2 is used, and an adhesive layer 4 is directly provided on the light reflection layer 3 to compose a light emitting body R. |
