    Abstract: A surface treatment agent includes: a fluorine-containing compound (A) having a reactive silyl group; and at least one compound (B) selected from the group consisting of a fluorine-containing ketone compound (B1): R1COR2, a fluorine-containing cyclic ketone compound (the following B2), and a fluorine-containing polyether compound (B3): R4—[OR5]q—R6. In Formula (B1), R1 and R2 represent a fluorine-containing alkyl group having from 1 to 5 carbon atoms. In Formula (B2), R3 represents a residue that forms a 3- to 5-membered ring structure with a carbon atom of a carbonyl group and that has a fluorine atom. In Formula (B3), R4 and R6 represent a fluorine-containing alkyl group having from 1 to 3 carbon atoms, q represents an integer of 1 or more, R5 represents a perfluoroalkylene group having from 1 to 6 carbon atoms, and in a case in which q is an integer of 2 or more, plural R5s may be the same or different.
