Abstract

Disclosed is a camera optical lens, comprising, from an object side to an image side in sequence: a first lens having a positive refractive power; a second lens having a negative refractive power; a third lens having a positive refractive power; a fourth lens having a positive refractive power; and a fifth lens having a negative refractive power; wherein, the camera optical lens satisfies: 12.50≤f3/f≤20.00; 0.30≤(R3+R4)/(R3−R4)≤1.00; and 0.30≤d5/d6≤0.50; where, f denotes a focus length of the camera optical lens; f3 denotes a focus length of the third lens; R3 and R4 denote central curvature radii of an object side surface and an image side surface of the second lens respectively; d5 denotes an on-axis thickness of the third lens; and d6 denotes an on-axis distance from the image side surface of the third lens to an object side surface of the fourth lens.
