Conventional methods using two optical waveguide members are disadvantageous in cost because they require two optical waveguide members and pairs of their associated components. A linear lighting apparatus includes a rod-like optical waveguide member () formed by a transparent material, a light source placed near an end face of the optical waveguide member () in the longitudinal direction, and a light exit surface () formed on at least part of the optical waveguide member () in the longitudinal direction. A cross section of the optical waveguide member in the widthwise direction has a plurality of reflecting areas () at positions to face a light exit surface () and a barrier () at a boundary portion between the reflecting areas ().
