Imaging Lens, and Electronic Apparatus Including the Same

An imaging lens comprising a first lens element, a second lens element, a third lens element, a fourth lens element and a fifth lens element arranged in order from an object side to an image side along an optical axis of said imaging lens, each of said first lens element, said second lens element, said third lens element, said fourth lens element and said fifth lens element having a refractive power, an object-side surface facing toward the object side, and an image-side surface facing toward the image side, wherein:

• said first lens element has a negative refractive power;
• said second lens element has a positive refractive power, said object-side surface of said second lens element having a convex portion in a vicinity of a periphery of said second lens element;
• said object-side surface of said third lens element has a concave portion in a vicinity of a periphery of said third lens element, and said image-side surface of said third lens element has a convex portion in a vicinity of a periphery of said third lens element;
• said image-side surface of said fourth lens element has a convex portion in a vicinity of the optical axis;
• said object-side surface of said fifth lens element has a concave portion in a vicinity of the optical axis, and said fifth lens element is made of a plastic material;
• and
• said imaging lens does not include any lens element with refractive power other than said first lens element, said second lens element, said third lens element, said fourth lens element and said fifth lens element.
