Claim Text:
1. A light emitting module, comprising: a flat plate-shaped light emitting panel having a light emitting surface on one surface; and a wiring board which is mounted on a non-light emitting surface located to an opposite side of the light emitting surface of the light emitting panel to supply power to the light emitting panel, wherein the light emitting module further includes an auxiliary wiring board which electrically connects the light emitting panel to the wiring board, the light emitting panel has an organic EL device as a light source, and electrode extraction units provided on the non-light emitting surface and derived from electrodes of the organic EL device, the wiring board has a conductive metal land provided on a surface located opposite to a surface which is mounted on the light emitting panel, the auxiliary wiring board has an electrode pad provided on a surface facing the light emitting panel and electrically connected to the electrode extraction units and a conductive metal pad provided on a surface located to an opposite side of the surface on which the electrode pad is located and electrically connected to the electrode pad, and the metal pad is wire-bonded to the metal land by using a conductive metal wire, and both ends of the metal wire are joined to the metal pad and the metal land by ultrasonic joining.
