The utility model provides an ultra-wide-angle high-pixel built-in lens of a mobile phone. The ultra-wide-angle high-pixel built-in lens sequentially comprises a first lens combination with a negativefocal length, a diaphragm, a second lens combination with a positive focal length and an optical filter from an object side to an image side, wherein the first lens combination comprises a first lenswith negative focal power and a second lens with positive focal power which are sequentially arranged along a light entering path; the second lens combination comprises a third lens, a fourth lens, afifth lens and a sixth lens which are sequentially arranged along a light entering path, the third lens and the fifth lens have positive focal power, and the fourth lens and the sixth lens have negative focal power; each of the lenses is an aspheric resin lens. According to the lens, the maximum field angle is increased; meanwhile, the requirement on the resolution of the lens is ensured; the maximum field angle FOV of the
