Camera optical lens

A camera optical lens, comprising, from an object side to an image side:

• a first lens having a positive refractive power;
• a second lens having a positive 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 following conditions:
• 1.20≤f2/f1≤7.00;
• −3.62≤(R1+R2)/(R1−R2)≤−1.18
• 1.50≤R6/R5≤5.00
• 1.20≤d5/d6≤2.00;
• where
• f1 denotes a focal length of the first lens;
• f2 denotes a focal length of the second lens;
• R1 denotes a central curvature radius of an object side surface of the first lens;
• R2 denotes a central curvature radius of an object side surface of the first lens;
• R5 denotes a central curvature radius of an object side surface of the third lens;
• R6 denotes a central curvature radius of an image side surface of the third lens;
• d5 denotes an on-axis thickness of the third lens;
• and
• d6 denotes an on-axis distance from the image side surface of the third lens to an object side surface of the fourth lens.
