A plastic lens of a multilayer film structure forms an organosiloxane-based hard coating film formed on a surface of a lens substrate as a first layer, an inorganic oxide-based antireflection film formed on the hard coating film as a second layer, and a water-repellent thin film obtained by polycondensing an organosilicon compound and formed on the antireflection film as a third layer, pencil hardness of the surface of the lens on which these plural layer films are formed being from 3H to 7H, and an initial falling angle of oleic acid on the surface of the lens on which these plural layer films are formed being 20° or less.
