A radiation-sensitive resin composition that provides a resist coating film in a liquid immersion lithography process is provided, the radiation-sensitive resin composition being capable of exhibiting a great dynamic contact angle during exposure, whereby the surface of the resist coating film can exhibit a superior water draining property, and the radiation-sensitive resin composition being capable of leading to a significant decrease in the dynamic contact angle during development, whereby generation of development defects can be inhibited, and further shortening of a time period required for change in a dynamic contact angle is enabled. A radiation-sensitive resin composition including (A) a fluorine-containing polymer having a structural unit (I) that includes a group represented by the following formula (1), and (B) a radiation-sensitive acid generator.

A radiation-sensitive resin composition includes (A) a polymer that includes an acid-labile group, (B) an acid generator that generates an acid upon exposure to radiation, and (C) a polymer that includes a fluorine atom and a functional group shown by the following general formula (x), the polymer (C) having a fluorine atom content higher than that of the polymer (A).
— A—R1 (x)
wherein R1 represents an alkali-labile group, and A represents an oxygen atom (excluding an oxygen atom that is bonded directly to an aromatic ring, a carbonyl group, or a sulfoxyl group), an imino group, -CO-O-*, or -SO2-O-* (wherein "*" indicates a bonding hand bonded to R1).
