Abstract

The present invention relates to the technical field of optical lens and discloses a camera optical lens satisfying following conditions: −0.50≤f1/f2≤−0.35; 5.00≤f3/f≤14.00; −3.10≤(f2+f5)/f≤−2.40; 3.00≤(R3+R4)/(R3−R4)≤4.00; 1.20≤(R7+R8)/(R7−R8)≤1.30; 0.25≤(R9+R10)/(R9−R10)≤0.65; where f denotes a focal length of the camera optical lens; f1, f2, f3 and f5 respectively denote a focal length of the first, second, third and fifth lenses; R3, R7 and R9 respectively denote a curvature radius of an object-side surface of the second, fourth and fifth lenses; R4, R8 and R10 respectively denote a curvature radius of an image-side surface of the second, fourth and fifth lenses.
