The camera optical lens  10  further satisfies the following condition: −10≤f1/f≤−3.1, which fixes the negative refractive power of the first lens L 1 . If the upper limit of the set value is exceeded, although it benefits the ultra-thin development of lenses, the negative refractive power of the first lens L 1  will be too strong, problem like aberration is difficult to be corrected, and it is also unfavorable for wide-angle development of lens. On the contrary, if the lower limit of the set value is exceeded, the negative refractive power of the first lens L 1  becomes too weak, it is then difficult to develop ultra-thin lenses.

     For convenience, the aspheric surface of each lens surface uses the aspheric surfaces shown in the above condition (1). However, the present invention is not limited to the aspherical polynomials form shown in the condition (1). 
     Table 3 shows the inflexion points design data of the camera optical lens  10  lens in embodiment 1 of the present invention. Table 4 shows the arrest point design data of the camera optical lens  10  lens in embodiment 1 of the present invention. In which, R 1  and R 2  represent respectively the object side surface and image side surface of the first lens L 1 , R 3  and R 4  represent respectively the object side surface and image side surface of the second lens L 2 , R 5  and R 6  represent respectively the object side surface and image side surface of the third lens L 3 , R 7  and R 8  represent respectively the object side surface and image side surface of the fourth lens L 4 , R 9  and R 10  represent respectively the object side surface and image side surface of the fifth lens L 5 , R 11  and R 12  represent respectively the object side surface and image side surface of the sixth lens L 6 , R 13  and R 14  represent respectively the object side surface and image side surface of the seventh lens L 7 . The data in the column named “inflexion point position” are the vertical distances from the inflexion points arranged on each lens surface to the optic axis of the camera optical lens  10 . The data in the column named “arrest point position” are the vertical distances from the arrest points arranged on each lens surface to the optic axis of the camera optical lens  10 .
