PROBLEM TO BE SOLVED: To provide a linear light guide and the like capable of acquiring longer light emitting length or improving illuminance.SOLUTION: A linear light guide 1 is mainly constituted by a side surface light-emitting type optical fiber 3, a flexible resin sheet 5 and the like. The side surface light-emitting type optical fiber 3 has flexibility, and the light entered a core diffuses from the side surface via a clad. The flexible resin sheet 5 is molded into a shape corresponding to an outer surface shape of the side surface light-emitting type optical fiber 3 beforehand. The flexible resin sheet 5 is, for example, formed from a micro foaming resin sheet. On an outer peripheral surface of the side surface light-emitting type optical fiber 3, a portion covered by the flexible resin sheet 5 is a covered part 7. Also, a portion which is not covered by the flexible resin sheet 5 and in which the outer peripheral surface of the side surface light-emitting type optical fiber 3 is exposed is an opening 9. At this time, it is desirable that the covered part 7 is formed more than a half periphery in the circumferential direction of the side surface light-emitting type optical fiber 3.SELECTED DRAWING: Figure 3

    【課題】 より長い発光長を得るかあるいは照度を向上させることが可能な線状ライトガイド等を提供する。【解決手段】 線状ライトガイド1は、主に、側面発光型光ファイバ3、可撓性樹脂シート5等から構成される。側面発光型光ファイバ3は、可撓性を有し、コアに入射した光がクラッドを介して側面から拡散するものである。可撓性樹脂シート5は、側面発光型光ファイバ3の外面形状に対応する形状にあらかじめ成形される。可撓性樹脂シート5は、例えば、マイクロ発泡樹脂シートから形成される。側面発光型光ファイバ3の外周面において、可撓性樹脂シート5で覆われた部位を被覆部7とする。また、可撓性樹脂シート5で覆われずに、側面発光型光ファイバ3の外周面が露出する部位を開口部9とする。この際、被覆部7は、側面発光型光ファイバ3の円周方向の半周以上に形成されることが望ましい。【選択図】図3
