It is an object of the present invention to provide a urethane (meth)acrylate that enables formation of a cured layer having a low reflectance and excellent excoriation resistance, a curable composition produced by using the same, and an antireflective film. In particular, there is provided a fluorine-containing urethane (meth)acrylate represented by General Formula (I) and having a fluorine atom content ranging from 25 to 60 mass % (where R
