Provided is a surface treatment agent comprising (A) a fluorine-containing polymer including a repeat unit derived from a fluorine-containing monomer (A1) and a repeat unit derived from a hydrocarbon group-bearing fluorine-free monomer (A2), and (B) a liquid medium. The fluorine-free monomer (A2) is preferably at least one monomer selected from the group consisting of (A2-1) R22-C(=O)-NH-R23-O-R21, (A2-2) CH2=C(-R32)-C(=O)-Y31-Z31(-Y32-R31)n, and (A2-3) X41N(H)r-R41. The surface treatment agent imparts an excellent water/oil repellency to base materials, e.g., fibers. L'invention concerne un agent de traitement de surface comprenant (A) un polymère contenant du fluor comprenant une unité de répétition dérivée d'un monomère contenant du fluor (A1) et une unité de répétition dérivée d'un monomère sans fluor portant un groupe hydrocarboné (A2), et (B) un milieu liquide. Le monomère sans fluor (A2) est de préférence au moins un monomère choisi dans le groupe constitué de (A2-1) R22-C(=O)-NH-R23-O-R21, (A2-2) CH2=C(-R32)-C(=O)-Y31-Z31(-Y32-R31)n, et (A2-3) X41N(H)r-R41. L'agent de traitement de surface confère une excellente répulsion de l'eau/huile à des matériaux de base, par exemple des fibres. （Ａ）含フッ素単量体（Ａ１）から誘導された繰り返し単位および炭化水素基を有する非フッ素単量体（Ａ２）から誘導された繰り返し単位を有する含フッ素重合体、および（Ｂ）液状媒体を含んでなる表面処理剤が提供される。非フッ素単量体（Ａ２）は、 （Ａ２－１）　Ｒ２２－Ｃ(＝Ｏ）－ＮＨ－Ｒ２３－Ｏ－Ｒ２１ （Ａ２－２）　ＣＨ2＝Ｃ(－Ｒ３２)－Ｃ(＝Ｏ)－Ｙ３１－Ｚ３１（－Ｙ３２－Ｒ３１)ｎ、および （Ａ２－３）　Ｘ４１Ｎ（Ｈ）ｒ－Ｒ４１ からなる群から選択された少なくとも１種の単量体であることが好ましい。表面処理剤は繊維などの基材に、優れた撥水撥油性を与える。
