An image capturing lens which substantially consists of five lenses, composed of a first lens having a positive refractive power with the object side surface being formed in a convex shape toward the object side, a second lens having a negative refractive power, a third lens having a positive refractive power, a fourth lens having a negative refractive power with the object side surface being formed in a concave shape toward the object side, and a fifth lens having a negative refractive power with a region in which the negative refractive power is gradually reduced outwardly in a radial direction from the optical axis, arranged in this order from the object side, and satisfies predetermined conditional expressions.
