The present invention has an object to provide a planar light-emitting panel attached with a jacket to protect edges of a light-emitting tile, while the jacket is prevented from being peeled off or removed from the light-emitting tile. The planar light-emitting panel includes the light-emitting using a glass substrate as a base, and an elastic jacket covering end faces of the glass substrate. An emission surface is provided on a front face of the light-emitting tile. The elastic jacket has a rear face side opening, on a rear face side of the light-emitting tile. On opening edges of the rear face side opening, when viewed from rear, a plurality of jacket side protrusions protruding toward a center side of the rear face side opening are formed. The jacket side protrusions are separated at predetermined intervals along the opening edges.
