description An optical imaging lens includes first to seventh lens elements sequentially arranged along an optical axis from an object side to an image side, wherein each of the first lens element to the seventh lens element includes an object-side surface facing the object side and allowing an imaging ray to pass through and an image-side surface facing the image side and allowing the imaging ray to pass through. The first lens element has positive refracting power, and a periphery region of the image-side surface of the first lens element is concave. The second lens element has negative refracting power. An optical axis region of the image-side surface of the third lens element is convex. An optical axis region of the image-side surface of the fourth lens element is concave. The sixth lens element has negative refracting power. In particular, the optical imaging lens only has seven lens elements.
