To provide an EL capable of perfectly preventing penetration of moisture and having high moisture resistance.
A luminescent part 8 formed by stacking a transparent electrode 3, a luminescent layer 5, a dielectric layer 6, and a back plate 4 is integratedly formed on the inner surface of either one glass substrate of a pair of faced glass substrates 1, 2, a through hole 1a is installed in the upper glass substrate 1, an (Ag-Pd) paste coating.baking film 13 is formed in the inner diameter part of the through hole 1a, a Cr-Ni-Ag deposition film 13 is formed on the upper surface, a taking-out electrode 4b is formed with silver paste on a conductive pattern 4a being taken out of the back plate 4, a metal terminal plate 15 having an L-shaped cross section is fixed to the taking-out electrode 4b through an anisotropic conductive adhesive, the upper part of the metal terminal plate 15 is made to project into the through hole 1 a, and sealed by soldering with solder 16. Moisture resistance is substantially increased and reliability of an EL is enhanced.
