Provided is a camera optical lens including first to seventh lenses. The camera optical lens satisfies following conditions: 1.50≤d1/d13≤3.00; 5.00≤(d1+d2)/d6≤8.00; and −50.00≤(R5+R6)/(R7+R8)≤−5.00, where d1 and d13 denote on-axis thicknesses of the first and seventh lenses, respectively; d2 denotes an on-axis distance from an image side surface of the first lens to an object side surface of the second lens; d6 denotes an on-axis distance from an image side surface of the third lens to an object side surface of the fourth lens; R5 and R6 denote curvature radiuses of an object side surface and the image side surface of the third lens, respectively; and R7 and R8denote curvature radiuses of the object side surface and an image side surface of the fourth lens, respectively. The camera optical lens can achieve high optical performance while satisfying design requirements for ultra-thin, wide-angle lenses having large apertures.
