PROBLEM TO BE SOLVED: To provide the manufacturing method of a layered product where an inorganic particulate layer excellent in strength is formed on a substrate. SOLUTION: The manufacturing method of the layered product where the inorganic particulate is formed on the substrate including a step of preparing a mixture inorganic particulate dispersion where an inorganic particulate (A) and an inorganic particulate (B) satisfying all the following conditions (1) to (3) are dispersed in a liquid dispersion medium, a step of coating the mixture inorganic particulate dispersion onto the substrate, and a step of forming the inorganic particulate layer on the substrate by removing the liquid dispersion medium from the dispersion coating the substrate. (1) Mean particle diameter Da of inorganic particulate (A) is 1-20 nm, mean particle diameter Db of inorganic particulate (B) is 30-300 nm, Da≤0.15Db, (2) 0.01≤Vca/(Vca+Vcb)≤0.40, and 0.60≤Vcb/(Vca+Vcb)≤0.99, however, Vca=Wa/da, Vcb=Wb/db, wherein Wa: weight of inorganic particulate (A) in mixture inorganic particulate dispersion, Wb: weight of inorganic particulate (B) in mixture inorganic particulate dispersion, da: density of inorganic particulate (A), db: density of inorganic particulate (B), and(3) 0.01≤(Wa+Wb)/Wt≤0.20, however, Wt: weight of mixture inorganic particulate dispersion.
