Imaging Lens, Imaging Apparatus and Mobile Terminal Device

An imaging lens in which an optical component including a lens base plate being a parallel flat plate and a lens section which is formed on at least one of an object side surface and an image side surface of the lens base plate and has a positive or negative power, is called a lens block;

• the imaging lens comprises a first lens block and a second lens sequentially from an object side,
• wherein the first lens block has a convex surface facing the object side and a concave surface facing the image side and has a positive power,
• an aperture stop is disposed at the object side of the first lens block or at the inside of the first lens block,
• a peripheral portion on the image side surface of the second lens has a positive power, and
• the following conditional expressions are satisfied,
• 0.62<fla/f<0.82 (1)
• −4.00<flb/f<−1.11 (2)
• 0.70<D4/f<1.00 (3)
• where fla represents the focal length of the object side lens section of the first lens block,
• flb represents the focal length of the image side lens section of the first lens block,
• D4 represents a distance on the optical axis from the object side surface of the first lens block to the image side surface of the second lens, and
• f represents the focal length of the imaging lens whole system.
