To provide a compact linear light-emitting body eliminating breakage of glass, providing a sufficient side light emission, and reducing restrictions on an installation place.

This linear light-emitting body is provided with linear light emitting means 1, a light source 2, and lighting means 3 of the light source. The light emitting means 1 comprises, at least, a transparent core material 1A, the light source 2 is disposed in a position capable of guiding the light in the length direction of the light emitting means 1, and the lighting means is a circuit lighting the light source by a charge/discharge current of a capacitor 3B using an AC power supply 3A. This linear light emitting body is so formed that the incident light from the light source 2 is irradiated from the length direction side of the light emitting means 1.
