An optical imaging lens including a first to a seventh lens elements arranged in sequence from an object side to an image side along an optical axis is provided. Each lens element includes an object-side surface and an image-side surface. A periphery region of the object-side surface of the second lens element is convex. An optical axis region of the image-side surface of the third lens element is concave. The fifth lens element has negative refracting power and a periphery region of the object-side surface of the fifth lens element is concave. Furthermore, the optical imaging lens satisfies the condition expression: ALT/T1≤4.500.
