Abstract
An imaging lens includes first, second, third, fourth, fifth and six lens elements arranged in order from an object side to an image side along an optical axis. Each lens element has an object-side surface and an image-side surface. The image-side surface of the second lens element has a concave portion in a vicinity of the optical axis. The third lens element has negative refractive power. The object-side surface of the third lens element has a concave portion in a vicinity of the optical axis. The object-side surface of the fifth lens element has a convex portion in a vicinity of a periphery. All lens elements of the imaging lens having the refractive power are only the first, second, third, fourth, fifth and six lens elements.
