Claim 10:
11. The camera optical lens as described in claim 1, further satisfying following conditions:

−1.35≤f9/f≤−0.39;

0.23≤(R17+R18)/(R17−R18)≤1.47; and

0.02≤d17/TTL≤0.08,

where
f9 denotes a focal length of the ninth lens,
R17 denotes a central curvature radius of an 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.
