Discloses is a camera optical including nine lenses, and the nine lenses from an object side to an image side are: a first lens with a negative refractive power, a second lens with a positive refractive power, a third lens with a positive refractive power, a fourth lens with a positive refractive power, a fifth lens with a positive refractive power, a sixth lens with a negative refractive power, a seventh lens with a negative refractive power, an eighth lens with a positive refractive power and an ninth lens with a negative refractive power. The camera optical lens satisfies: −1.90≤f1/f≤−0.70; 1.50≤d5/d6≤8.00; −18.00≤f6/f≤−3.00. The camera optical lens has good optical performance, and meets the design requirements of a large aperture wide-angle and ultra-thin.
