Imaging Lens and Electronic Apparatus Having the Same

An imaging lens comprising an aperture stop, first, second, third, fourth, and fifth lens elements arranged from an object side to an image side in the given order, wherein:

• said first lens element has a positive refractive power;
• said second lens element has a negative refractive power;
• said third lens element has a negative refractive power, and has an image-side surface that faces toward the image side and that has a first convex portion in a vicinity of a periphery of said third lens element;
• said fourth lens element has an object-side surface facing toward the object side, said object-side surface of said fourth lens element being a concave surface;
• said fifth lens element has an object-side surface and an image-side surface that face toward the object side and the image side, respectively, said object-side surface of said fifth lens element having a first convex portion in a vicinity of an optical axis of said imaging lens, said image-side surface of said fifth lens element having a concave portion in a vicinity of the optical axis and a convex portion in a vicinity of a periphery of said fifth lens element;
• and
• said imaging lens does not include any lens element with refractive power other than said first, second, third, fourth, and fifth lens elements.
