Abstract: The present invention addresses the problem of providing a manufacturing method for an electronic device that is provided with an organic thin film functioning as a sealing film against moisture permeation in an electronic device such as an organic electroluminescence element. This manufacturing method for an electronic device is a manufacturing method for an electronic device that has at least an organic functional layer, an elution prevention film, and a sealing film in this order, said manufacturing method being characterized by having: a step in which, after coating is performed with a silicone resin, the result is irradiated with vacuum ultraviolet rays to form the elution prevention film; and a step in which, after the elution prevention film is coated with a liquid mixture of a metal alkoxide and a fluoroalcohol, the result is irradiated with vacuum ultraviolet rays to form the ultraviolet rays to form the sealing film.

Abstract: The present invention addresses the problem of providing a desiccant that can be used for passivation of an electronic device such as an organic electroluminescence element against moisture permeation, as well as an organic thin film including the desiccant, an organic layered film in which the organic thin film is layered, and an electronic device that is provided therewith. This desiccant is characterized by including a compound that emits a hydrophobic substance by absorbing water. This organic thin film is characterized by including this desiccant.
