The present disclosure relates to the field of optical lenses and provides a camera optical lens sequentially including, from an object side to an image side, first to seventh lenses. The camera optical lens satisfies following conditions: 2.00≤R1/d1≤4.00; 20.00≤v4−v5≤30.00; 1.00≤(R1+R2)/(R3+R4)≤2.50; and 1.00≤R12/R11≤2.80, where v4 and v5 denote abbe numbers of the fourth and fifth lenses, respectively; R1 and R2 denote curvature radiuses of an object side surface and an image side surface of the first lens, respectively; R3 and R4 denote curvature radiuses of an object side surface and an image side surface of the second lens, respectively; R11 and R12 denotes curvature radiuses of an object side surface and an image side surface of the sixth lens, respectively; and dl denotes an on-axis thickness of the first lens. The camera optical lens can achieve high optical performance while satisfying design requirements for ultra-thin, wide-angle lenses having large apertures.
