Zusammenfassung:	To provide a lighting method capable of increasing light volume that an object to be imaged receives.SOLUTION: A lighting method comprises: arranging a linear lighting unit 11 that has a plurality of light sources 13 arranged linearly in one direction, and a lighting system condenser lens 14 for condensing lighting light L10 generated from the plurality of light sources 13; arranging an optical waveguide 12 that emits the lighting light L10, which is condensed by the lighting system condenser lens 14 and made incident on an upper end face 12c, from a lower end face 12d, wherein the optical waveguide 12 has the upper end surface 12c extending in one direction and the lower end surface 12d opposite to the upper end surface 12c; and lighting an object to be imaged 40 with the lighting light L10 emitted from the optical waveguide 12.SELECTED DRAWING: Figure 1 【課題】撮像対象が受光する光量を増加させることができる照明方法を提供する。【解決手段】本発明に係る照明方法は、一方向にライン状に並んだ複数の光源１３と、複数の光源１３から生成された照明光Ｌ１０を集光する照明系集光レンズ１４と、を有するライン状照明部１１を配置させるステップと、一方向に延在した上端面１２ｃ及び上端面１２ｃに対向する下端面１２ｄを有する光導波路１２であって、照明系集光レンズ１４で集光され、上端面１２ｃに入射した照明光Ｌ１０が下端面１２ｄから出射する光導波路１２を配置させるステップと、光導波路１２から出射した照明光Ｌ１０で撮像対象４０を照明するステップと、を備える。【選択図】図１
