Abstract
To provide a waterproof surface-emitting panel and a method for manufacturing the same, which can be easily modified in shape and size. [Solution] A surface-emitting panel comprising: a light guide plate that diffuses light and has a surface that serves as a light-emitting surface; an LED lamp mounted on a printed circuit board; and a heat dissipation section having at least one bent portion, which is arranged to have a portion that contacts the back surface of the printed circuit board and a portion that contacts the surface of the light guide plate and / or the surface opposite it, wherein the space having the LED lamp mounted on the printed circuit board is sealed by the heat dissipation section and resin, and / or the periphery of the portion of the heat dissipation section that contacts the surface of the light guide plate and / or the surface opposite it, and the portion of the surface of the light guide plate and / or the surface opposite it that contacts the periphery of the heat dissipation section are covered with resin, and the seepage of resin into the gap between the heat dissipation section and the surface of the light guide plate and / or the surface opposite it is 10 mm or less.
