A linear light guide is mainly made up of a side emission type optical fiber, a flexible resin sheet, etc. The side emission type optical fiber is flexible and allows light entering a core to diffuse from its side via a clad. The flexible light resin sheet is preliminarily formed conformity to an external form of the side emission type optical fiber. The flexible light resin sheet is formed from, e.g., a microcellular structure resin sheet. A portion covered with the flexible light resin sheet in an outer circumferential surface of the side emission type optical fiber is defined as a covered section, while a portion not covered with the flexible light resin sheet to expose the outer circumferential surface of the side emission type optical fiber is defined as an opened section.
