A light emitting apparatus includes: a sealing member () forming a sealing region sealing a planar light emitting unit; and a wiring member () including a conductive unit () electrically connected to the planar light emitting unit and extending from the sealing region to an outside. The sealing member () has a drawing port opened at a periphery of the sealing member for drawing the wiring member () to the outside. The wiring member () includes: an internal wiring portion () in which the conductive unit () is disposed in the sealing region; an external wiring portion () in which the conductive unit () is disposed in the outside; and a boundary wiring portion () in which the conductive unit () is disposed in the drawing port and which has a smaller thickness than the internal wiring portion () and/or the external wiring portion (). Such a configuration provides a light emitting apparatus having a sealing structure of the planar light emitting unit for suppressing deterioration of sealing performance due to disposition of the wiring member.

A light-emitting device includes a surface-light-emitting unit, a substrate, a holding sheet, and a sealing sheet. The surface-light-emitting unit has a light-emitting surface and a non-light-emitting surface, and emits light from the light-emitting surface. The substrate has a mounting surface and a non-mounting surface provided to be flush with the light-emitting surface, and has a power source mounted on the mounting surface. The holding sheet is provided to face the non-mounting surface and the light-emitting surface provided to be flush with the non-mounting surface. The sealing sheet is disposed on the side opposite to the holding sheet with respect to the surface-light-emitting unit and the substrate, and provided to cover the surface-light-emitting unit and the power source. The light-emitting device is disposed so that the holding sheet comes to the installation surface side. With such a structure, the light-emitting device that can be stably disposed on the installation surface is provided.

In a surface light-emitting unit, a wiring board () includes, on its side on which a holding substrate () is located, an external-wire connecting portion (). An opening () is provided in the holding substrate (). The wiring board () is disposed to cover the opening () and allow the external-wire connecting portion () to be exposed, through the opening (), toward a surface of the holding substrate () opposite to the surface thereof on which the wiring board () is held. With an external wire connected to the external-wire connecting portion (), a surface of the wiring board () located in the opening () is sealed by a second sealing member.

A lighting apparatus may include a holding member, a lighting panel, and an attachment bracket for removably attaching the lighting panel to the holding member. The lighting panel may form a first position in which a light-emitting surface of the lighting panel and a light-emitting surface of a lighting panel are located substantially on the same plane with each other and a second position in which the lighting panel is pressed from its light-emitting surface side so that the attachment bracket pivots around a portion where the attachment bracket is attached to the holding member and the lighting panel is inclined with respect to the lighting panel. As the lighting panel forming the second position is moved in a direction away from the holding member the attachment bracket is released from the holding member, and the lighting panel forming the second position is readily removed from the holding member.
