[Problem to be Solved] n Provided is a coating composition excellent in antifouling properties, transparency and hydrophilicity and capable of maintaining surface hydrophilicity even at high temperature. n [Solution] n A coating composition containing n(A) a metal oxide particle having a number average particle size of 1 nm to 400 nm, and n(B) a polymer particle, n nin which the content of an aqueous-phase component in the component (B), represented by the following expression (I), is 20 mass% or less. The content of the aqueous - phase component % = dry mass of a filtrate obtained by filtering the component B at a molecular cutoff of 50 , 000 × 100 - total mass of solid content / mass of the filtrate - dry mass of the filtrate × 100 / the total mass of solid content |
