The present invention discloses a camera optical lens. The camera optical lens includes, in an order from an object side to an image side, a first lens, a second lens, a third lens, a fourth lens, a fifth lens, and a sixth lens. The second lens has a negative refractive power, and the third lens has a positive refractive power. The camera optical lens further satisfies the specific conditions: 0.80≤f1/f≤5.00 and −11.00≤R5/d5≤−8.00. The camera optical lens can achieve a high performance while obtaining a low TTL.
