PURPOSE: To eliminate a gap between light emitting diodes even when light emitting dots are arranged in a line. CONSTITUTION: Multiple light emitting dots 2 to be a light emitting part are arranged in a line at an equal interval. A plane shape of the light emitting dot 2 is formed into a protrusion-shape. A protrusion-shape head part 2a is directed in the direction orthogonal to the direction of arranging the light emitting dot 2, and the protrusion-shape head parts 2a of adjoining light emitting dots 2 are directed in the opposite directions to each other. The light emitting dots 2 are brought close to each other in the arrangement direction, so that in a root part 2c of the protrusion shape head part 2a of the light emitting dot 2, a protrusion-shape shoulder part 2d of the adjoining dot 2 may be fitted. |
