ABSTRACT:
An illumination device comprising: a wired board having flexibility and including a light source member mounted on one of principal planes; a light-shielding member disposed so as to cover at least part of the other principal plane of the wired board on the opposite side from the one principal plane and having at least partly a light-shielding property; a fixing member having first and second sticking surfaces to which the wired board and the light-shielding member are stuck respectively, a first adhesive layer being interposed between the one principal plane of the wired board and the first sticking surface of the fixing member, having an adhesive property with respect to both of the one principal plane of the wired board and the first sticking surface, and having a first adhesive force with respect to the one principal plane, and a second adhesive layer being disposed on a surface opposing the fixing member of the light-shielding member, and having a portion having an adhesive property with respect to both of the light-shielding member and the second sticking surface and a portion having an adhesive property for both of the light-shielding member and the other principal plane of the wired board, wherein the second adhesive layer includes a non-adhesive portion having no adhesive property with respect to the other principal plane or a low-bond strength adhesive portion having a second adhesive force lower than the first adhesive force at least in a portion having an adhesive force for both the light-shielding member and the other principal plane of the wired board.
