PROBLEM TO BE SOLVED: To provide a transparent electrical conductive film for an electroluminescence element, which keeps its performance stably for a long time even when it is lit continuously using an inverter in a high humidity atmosphere as a packageless electroluminescence element, has performances such as high luminance and low power consumption, and adheres closely on a light emitting body layer satisfactorily. SOLUTION: This transparent electrical conductive film for a electroluminescence element is formed by accumulating a transparent polymer film, a transparent electrical conductive layer which is made of indium oxide (In2 O3 ) - tin oxide (SnO2 ) sintered body containing 3 to 15 wt.% of tin oxide (SnO2 ) and has a thickness of 100 to 500Å, and a high dielectric constant resin layer which is made of cyanoalkyl retermed fluororesin having dielectric constant >=10 and has a thickness (x) of 3 to 10μm sequentially on at least one face of the transparent polymer film. When this transparent conductive film for EL is used as, in particular, an electrode for EL, close adhesion on a light emitting body layer can be increased owing to the high dielectric constant resin layer on the transparent conductive layer. Moreover, it is possible to obtain an EL which does not cause a non-light lit part on the surface of a light emitting body of an EL element and has by far excellent durability, even if the EL is continuously lit in a high humidity atmosphere.
