1. An optical imaging lens, from an object side to an image side in order along an optical axis 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, the first lens element to the seventh lens element each having an object-side surface facing toward the object side and allowing imaging rays to pass through as well as an image-side surface facing toward the image side and allowing the imaging rays to pass through, wherein:
the first lens element has negative refracting power;
the second lens element has positive refracting power;
an optical axis region of the image-side surface of the third lens element is convex;
a periphery region of the object-side surface of the fourth lens element is concave;
the fifth lens element has positive refracting power; and
an optical axis region of the image-side surface of the seventh lens element is concave;
wherein only the above-mentioned seven lens elements of the optical imaging lens have refracting power;
wherein, TTL is a distance from the object-side surface of the first lens element to an image plane along the optical axis, T4 is a thickness of the fourth lens element along the optical axis and T5 is a thickness of the fifth lens element along the optical axis, and the optical imaging lens satisfies the relationship: TTL/(T4+T5)≤7.500 and a thickness of the second lens element along the optical axis is smaller than a thickness of the seventh lens element along the optical axis.
