A radiation-sensitive resin composition includes a first polymer including an acid-labile group, an acid generator to generate an acid upon exposure to radiation, and a second polymer including a fluorine atom and a functional group shown by a general formula (x). The second polymer has a fluorine atom content higher than a fluorine atom content of the first polymer. R
