PROBLEM TO BE SOLVED: To provide a technique capable of imparting excellent wear resistance to a liquid repellent layer. SOLUTION: The composition of the present invention is a mixture of at least one metal compound (G) selected from a metal compound represented by the following formula (G1) and a condensate thereof, polysilazane (F), and a solvent (I). The composition is characterized in that the amount of polysilazane (F) is 0.01% by mass or more and less than 50% by mass. M (R g10 ) r (A g1 ) mr (G1) [In formula (G1), M represents Al, Fe, In, Ge, Hf, Si, Ti, Sn, Zr, or Ta, and R g10 represents a hydrocarbon chain-containing group or a hydrogen atom. Is 0 or 1. Each of the plurality of Ag1s independently represents a hydrolyzable group, and m is an integer of 3 to 5 depending on the metal atom M. ] [Selection diagram] None |
