PROBLEM TO BE SOLVED: To provide a method for producing a multilayer structure excellent in gas barrier properties under high-humidity conditions. SOLUTION: A method for producing a multilayer structure having a substrate layer, a first layer, and a second layer contiguous to the first layer comprises in the given order (1) the step of forming the first layer by coating the substrate layer with a first coating liquid containing a first fine inorganic particle, a first metal alkoxide, and a first aqueous medium to form a first coating film and removing the first aqueous medium from the first coating film and (2) the step of forming the second layer on the first layer by coating the first layer with a second coating liquid containing a second resin, a second inorganic layered compound, and a second liquid medium to form a second coating film and removing the second liquid medium from the second coating film. The average particle diameter of the first fine inorganic particle is 1μm or less. COPYRIGHT: (C)2009,JPO&INPIT
