Claim 8:
9. The camera optical lens as described in claim 1, further satisfying following conditions:

0.54≤f7/f≤4.63;

−1.70≤(R13+R14)/(R13−R14)≤−0.07; and

0.03≤d13/TTL≤0.14,

where
f7 denotes a focal length of the seventh lens,
R13 denotes a central curvature radius of an object side surface of the seventh lens,
R14 denotes a central curvature radius of an image side surface of the seventh lens,
d13 denotes an on-axis thickness of the seventh 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.
