Title

Abstract
(EN)

PROBLEM TO BE SOLVED: To provide an image capturing optical lens which offers high imaging performance and meets the demand for extreme thinness and a wider view angle.

SOLUTION: An image capturing optical lens comprises, in order from the object side to the image side, a first lens L1, a second lens L2, a third lens L3, a fourth lens L4, a fifth lens L5, and a sixth lens L6, the second lens L2 having positive refractive power and the third lens L3 having positive refractive power. The image capturing optical lens satisfies the following conditional expressions: 6.00≤f1/f≤10.00, -23.00≤R5/d5≤-10.00. where f represents a focal length of the image capturing optical lens 10, f1 represents a focal length of the first lens L1, R5 represents a curvature radius of an object-side surface of the third lens L3, and d5 represents a thickness of the third lens L3 along an optical axis.
