Imaging lens assembly, image capturing device and electronic device

The invention discloses a lens group of an imaging system. The lens group comprises six lenses. The six lenses are sequentially a first lens, a second lens, a third lens, a fourth lens, a fifth lens and a sixth lens from the object side to the image side along an optical path. Each of the six lenses has an object-side surface facing the object-side direction and an image-side surface facing the image-side direction. The first lens element has positive refractive power. The fifth lens element has an image-side surface being convex in a paraxial region thereof. The sixth lens element has an image-side surface being concave in a paraxial region thereof and having at least one inflection point. When specific conditions are met, the imaging system lens group can meet the requirements of long back focus, miniaturization and high imaging quality at the same time. The invention further discloses an image capturing device with the imaging lens assembly and an electronic device with the image capturing device. 本发明公开一种成
