An optical imaging lens includes a front lens group, a reflective element and a rear lens group arranged in sequence from an object side to an image side along an optical axis. The optical axis includes a first optical axis and a second optical axis different from the first optical axis, and the first optical axis and the second optical axis have an intersection point located at the reflective element. The front lens group includes a first lens element and a second lens element arranged along the first optical axis, and the rear lens group includes a third lens element and a fourth lens element arranged along the second optical axis. The optical imaging lens satisfies: D1M≦3.6 mm, wherein D1M is a distance from an object-side surface of the first lens element to the intersection point along the first optical axis.
