Provided are a surface treatment liquid capable of simply and efficiently realizing a hydrophobic treatment of a substrate, a hydrophobic treatment method using the surface treatment liquid, and a hydrophobicized substrate. The substrate is hydrophobized using a surface treatment liquid containing a silylating agent and a hydrocarbon nonpolar solvent. The silylating agent is preferably N, N-dimethylaminotrimethylsilane (DMATMS), and the hydrocarbon nonpolar solvent is a linear or branched hydrocarbon solvent having 6 to 12 carbon atoms, or a terpene solvent. Is preferred. [Selection] Figure 1 |
