A wide-angle image lens, in the order from the object side to the image side thereof, includes a first lens, a second lens, a third lens, a fourth lens, a fifth lens and an image plane. The wide-angle image lens satisfies the formulas: D/TTL>1.16;D/L>1.17;Z/Y>0, wherein D is the maximum image diameter of the wide-angle image plane; TTL is the total length of the wide-angle image lens; L is a distance from an outmost edge of an image surface of the fifth lens to an optical axis of the wide-angle image lens; Z is a distance from a central point of the objective surface of the fourth lens to an outmost edge of the image surface of the fourth lens, Y is a distance from the outmost edge of the image surface of the fourth lens to the optical axis.
