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

−1.66≤f9/f≤−0.50;

0.06(R17+R18)/(R17−R18)≤0.38; and

0.04≤d17/TTL≤0.14,

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 the total optical length from the object side surface of the first lens to the image plane of the camera optical lens along the optic axis.
