Abstract: Disclosed is a mobile terminal devised to achieve a reduced F-number and an increased T-number by enhancing the brightness of an optical system provided therein. In the mobile terminal including an optical module that configures a single optical system, the optical module includes a lens group configured with five or more refractive lenses including at least one glass lens. The glass lens has a thickness equal to or greater than 0.3 mm, an effective diameter equal to or greater than 1.5 mm and equal to or less than 8.0 mm, a refractive index below 1.6, and an Abbe's number equal to or greater than 60.
