Light-emitting device and mobile object

A light-emitting device comprising:

• a holder having an elongate shape and flexibility;
• and
• a flat light-emitting element held by the holder and having a rectangular shape and flexibility, the flat light-emitting element comprising:
• a pair of substrates;
• a pair of electrodes disposed between the pair of substrates and electrically connected to an anode and cathode;
• an extraction electrode extracted from each electrode of the pair of electrodes;
• and
• a light-emitting layer disposed between the pair of electrodes;
• wherein:
• the holder includes a frame extending in a longitudinal direction of the holder in a plan view, and a beam protruding from the frame and extending across the top of the light emitting layer in a latitudinal direction of the holder in a plan view and wherein the beam is configured to supply power to the flat light-emitting element via power supply units disposed on the beam,
• the frame of the holder and the beam overlap the light emitting element in an orthogonal direction in a plan view,
• the flat light-emitting element is joined to the frame and beam by a plurality of holding pieces, and
• the extraction electrodes are electrically and mechanically connected to the power supply units in a region where the power supply units and the flat light-emitting element are joined together.
