Claim 0:
1. A surface treatment agent, comprising:
a silylating agent (A) represented by General Formula (4);
a compound (C) represented by General Formula (c1);
a nitrogen-containing basic compound or a salt thereof (B), provided that a compound corresponding to the compound (C) is excluded; and
a solvent (S), provided that a compound corresponding to the compound (C) is excluded, wherein the content of the compound (C) with respect to the total amount of the surface treatment agent is greater than or equal to 0.1 mass % and less than or equal to 20 mass %,
the content of the solvent (S) with respect to the total amount of the surface treatment agent is greater than or equal to 70 mass % and less than or equal to 98 mass %,
wherein the nitrogen-containing basic compound is an aromatic nitrogen-containing heterocyclic compound containing a nitrogen-containing 5-membered ring,, wherein R4, R5, and R6 each independently represents a hydrogen atom, a nitrogen-containing group, or an organic group, and the total number of carbon atoms contained in R4, R5, and R6 is greater than or equal to 1, R9 represents a hydrogen atom, a methyl group, a trimethylsilyl group, or a dimethylsilyl group, R10, R11, and R12 each independently represents a hydrogen atom or an organic group, and the total number of carbon atoms contained in R10, R11, and R12 is greater than or equal to 1;, and Rc1 and Rc2 each independently represents a hydrogen atom or a hydrocarbon group which may have a substituent, and Rc3 represents a hydrogen atom, a nitrogen-containing group, or an organic group.
