Abstract: Provided is a surface treatment agent capable of imparting superior antifouling property as well as good and durable hydrophilicity to an inorganic substrate. The surface treatment agent is one comprising a pretreatment agent and a hydrophilizing treatment agent and being to be sequentially applied to an inorganic substrate, wherein the pretreatment agent comprises a silane compound having a reactive silyl group and an organic functional group and a polyfunctional monomer, and the polyfunctional monomer has one or more first reactive groups that react with the organic functional group and one or more second reactive groups that react with the hydrophilizing treatment agent.
