Abstract: A planar light-emitting module includes a sealing sheet having an opening, a sealing sheet, a planar light-emitting element sealed by the sealing sheets, and a wiring member disposed between the sealing sheets. The wiring member includes an electrode having an exposed portion disposed so as to be exposable from the opening of the sealing sheet and a protective film having an aperture corresponding to the exposed portion. An edge portion that forms the opening in the sealing sheet is located outside the aperture and located on a portion having a flat shape in a surface of the protective film. The planar light-emitting module can suppress reduction of sealing performance due to the presence of the wiring member.

Abstract: A light-emitting device (100) includes a housing (20) including a light-transmitting section (25), a surface light-emitting element (10) including a rectangular light-emitting section (R10) facing the light-transmitting section (25) and a non-light-emitting section formed outside the light-emitting section (R10), and an electronic device (31). The non-light-emitting section includes a flexible outer edge section (R13) provided with an electrode on a surface. The outer edge section (R13) is bent in a direction away from a light-emitting surface (S1) of the light-emitting section (R10) together with the electrode. The electrode electrically connects the light-emitting section (R10) and the electronic device (31).
