Abstract: A layered structure having high adhesive properties, and high hardness or excellent transparency, is prepared on a base material such as a resin. A layered structure including: an organic-inorganic hybrid member containing a primary inorganic particle and an organic polymer covalently bound to each other, wherein the primary inorganic particle forms a network containing the polymer; and a particle aggregate layer containing a secondary particle which is deposited on the organic-inorganic hybrid member and is composed of an inorganic material or a metallic material; wherein in the organic-inorganic hybrid member, the primary inorganic particle and the secondary particle have different crystal particle sizes.
