Claim 11:
12. A camera module, comprising an optical lens and an image sensor opposite to the optical lens, wherein, from an object side to an Imaging plane along an optical axis, the optical lens sequentially comprising:
a stop;
a first lens with a positive focal power, an object side surface of the first lens being convex;
a second lens with a negative focal power, an image side surface of the second lens being concave;
a third lens with a positive focal power, an object side surface of the third lens being convex and an image side surface of the third lens being concave;
a fourth lens with a positive focal power, an object side surface of the fourth lens being concave and an image side surface of the fourth lens being convex; and
a fifth lens with a negative focal power, a paraxial region of an object side surface of the fifth lens being concave, a paraxial region of an image side surface of the fifth lens being concave;
wherein an entrance pupil diameter EPD of the optical lens is smaller than 1.58 mm, and a distance between the orthogonal projection of an entrance pupil on the optical axis and the orthogonal projection of an edge of an effective optical portion of the object side surface of the first lens on the optical axis is greater than 0.17 mm.
