Abstract: An illumination device includes a light source member, a flexible wired board the light source member mounted thereon and a wiring provided thereon, and a structure to be stuck to the wired hoard via sticking members at a plurality of sticking surfaces, wherein one end of the wiring provided on the wired board is electrically connected to and terminated at the light source member, and the other end of the wiring is provided with a connecting path to be electrically connected to the outside, and wherein the bond strength of the plurality of sticking surfaces is set in such a manner that the bond strength of the sticking surface located on the one end side of the wiring is lower than that of the sticking surface located on the other end side of the wiring.

Abstract: A lighting device includes a board mounting a light source, a first hole provided in the board, a projecting part protruded inside the first hole from a periphery of the first hole, a light guide which receives a light emitted from the light source through a light receiving plane, and transmits the light from a light transmitting plane, and the first protrusion which is integrally formed in the light guide and is inserted into the first hole, wherein the projecting part presses a side of the first protrusion so that the board can move toward the light receiving plane.
