1. An optical imaging lens, comprising a first lens element, a second lens element, a third lens element, a fourth lens element, a fifth lens element, a sixth lens element and a seventh lens element sequentially from an object side to an image side along an optical axis, each of the first, second, third, fourth, fifth, sixth and seventh lens elements having an object-side surface facing toward the object side and allowing imaging rays to pass through and an image-side surface facing toward the image side and allowing the imaging rays to pass through, wherein:
the second lens element has negative refracting power;
the third lens element has negative refracting power, and an optical axis region of the object-side surface of the third lens element is concave;
an optical axis region of the object-side surface of the fifth lens element is concave, and a periphery region of the image-side surface of the fifth lens element is convex;
the sixth lens element has negative refracting power, and an optical axis region of the image-side surface of the sixth lens element is concave;
lens elements of the optical imaging lens are only the seven lens elements; and
a thickness of the fourth lens element along the optical axis is represented by T4, a distance from the image-side surface of the fourth lens element to the object-side surface of the fifth lens element along the optical axis is represented by G45, a thickness of the fifth lens element along the optical axis is represented by T5, a distance from the image-side surface of the fifth lens element to the object-side surface of the sixth lens element along the optical axis is represented by G56, and the optical imaging lens satisfies the inequality:
(T4+G45)/(T5+G56)≥1.500.
