造。 A light-emitting layer is interposed between a transparent electrode formed on one side of a transparent sheet and a counter electrode disposed opposite to the transparent electrode, and the light-emitting layer is hermetically covered with a protective sheet, and the protective sheet and the counter electrode are In an electroluminescent element, a moisture absorbing layer made of a material with high moisture absorption efficiency is interposed between the transparent sheet and the protective sheet, and the light emitting layer is caused to emit light by applying a voltage between the two electrodes. 1. A moisture-proof structure for an electroluminescent element, characterized in that a large number of depressions and depressions are formed on at least one of opposing surfaces, and gaps defined by these depressions and depressions are communicated with the moisture absorbing layer.
