Imaging lens, imaging device and portable terminal

An image pickup lens for forming an image of a subject onto an image pickup surface of a solid-state image pickup element where a diagonal length of the image pickup surface being 2Y, the image pickup lens comprising in order from an object side thereof:

• a first lens with a positive refractive power, comprising a convex surface facing the object side;
• a second lens with a negative refractive power, comprising two aspheric surfaces;
• a third lens with a negative refractive power, comprising an aspheric surface;
• a fourth lens with a positive refractive power, comprising a convex surface facing an image side;
• and
• a fifth lens with a negative refractive power,
• wherein there is a surface distance on the optical axis between each of the first to fifth lenses;
• an image-side surface of the fifth lens has an aspheric shape, and includes an inflection point at a position excluding an intersection point with an optical axis, and
• the image pickup lens satisfies the following conditional expressions:
• 20<v1−v2<70 (4)
• L/2Y<1.1 (10)
• where v1 is an Abbe number of the first lens,
• v2 is an Abbe number of the second lens, and
• L is a distance along the optical axis from a lens surface arranged at a closest position to the object side in a total system of the image pickup lens to a focal point at the image side.
