Claim 0:
1. A camera optical lens comprising, from an object-side to an image-side in sequence: a first lens having a positive refractive power, a second lens having a negative refractive power, a third lens having a negative refractive power, a fourth lens having a positive refractive power, and a fifth lens having a negative refractive power;
wherein the camera optical lens satisfies the following conditions:

−0.17≤f1/f2≤−0.12;

1.80≤d1/d2≤2.20;

0.15≤d6/d8≤0.20;

8.00≤(R3+R4)/(R3−R4)≤10.00;

11.00≤R7/f≤12.00;

where
f denotes a focal length of the camera optical lens;
f1 denotes a focal length of the first lens;
f2 denotes a focal length of the second lens;
d1 denotes an on-axis thickness of the first lens;
d2 denotes an on-axis distance from an image-side surface of the first lens to an object-side surface of the second lens;
d6 denotes an on-axis distance from an image-side surface of the third lens to an object-side surface of the fourth lens;
d8 denotes an on-axis distance from an image-side surface of the fourth lens to an object-side surface of the fifth lens;
R3 denotes a central curvature radius of the object-side surface of the second lens;
R4 denotes a central curvature radius of an image-side surface of the second lens;
R7 denotes a central curvature radius of the object-side surface of the fourth lens.
