Imaging lens, image capturing device and electronic device

The invention discloses an imaging lens, an image capturing device and an electronic device. The imaging lens is provided with an optical axis. The imaging lens comprises a plurality of optical elements, a lens barrel, an optical identification structure and a curable liquid. The optical elements are arranged along an optical axis. The optical element includes a non-circular element. The non-circular element includes a bearing portion. The lens barrel surrounds the optical axis. The non-circular element is housed in the lens barrel. The bearing part is in solid contact with the lens barrel. The bearing part is provided with a tangent plane. The optical identification structure is arranged in a first direction and is arc-shaped, and the optical identification structure comprises a plurality of optical identification units. The optical identification units are adjacently arranged along the circumferential direction surrounding the optical axis, and each optical identification unit comprises a first optical iden
