Claim 9:
10. The camera optical lens as described in claim 1, wherein the camera optical lens satisfies following conditions:

−5.32≤f9/f≤−1.35;

2.53≤(R17+R18)/(R17−R18)≤10.69; and

0.03≤d17/TTL≤0.10,

where
f9 denotes a focal length of the ninth lens;
R17 denotes a central curvature radius of the object side surface of the ninth lens;
R18 denotes a central curvature radius of an image side surface of the ninth lens;
d17 denotes an on-axis thickness of the ninth lens; and
TTL denotes a total optical length from an object side surface of the first lens to an image plane of the camera optical lens along an optic axis.
