An imaging lens of fixed focal length is formed of, in order from the object side, an aperture diaphragm, a first lens component having positive refractive power and having at least one aspheric lens surface, and a second lens component having positive refractive power and having at least one aspheric lens surface. The imaging lens satisfies two specified conditions so as to favorably correct distortion and curvature of field while providing a sufficient distance from the imaging lens to the exit pupil of the imaging lens. In addition, one or more of the lens components may each be formed of a single lens element.
