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.
