Claim 6:
7. The camera optical lens as described in claim 1, wherein the camera optical lens further satisfies following conditions:

−2.49≤f5/f≤−0.70;

1.09≤(R9+R10)/(R9−R10)≤4.08; and

0.04≤d9/TTL≤0.15,

where
f5 denotes a focal length of the fifth lens;
R9 denotes a curvature radius of the object side surface of the fifth lens;
R10 denotes a curvature radius of an image side surface of the fifth lens;
d9 denotes an on-axis thickness of the fifth lens; and
TTL denotes a total optical length from the object side surface of the first lens to an image plane of the camera optical lens along an optic axis.
