Abstract: A light-folding element includes an object-side surface, an image-side surface, a reflection surface and a connection surface. The reflection surface is configured to reflect imaging light passing through the object-side surface to the image-side surface. The connection surface is connected to the object-side, image-side and reflection surfaces. The light-folding element has a recessed structure located at the connection surface. The recessed structure is recessed from the connection surface an includes a top end portion, a bottom end portion and a tapered portion located between the top end and bottom end portions. The top end portion is located at an edge of the connection surface. The tapered portion has two tapered edges located on the connection surface. The tapered edges are connected to the top end and bottom end portions. A width of the tapered portion decreases in a direction from the top end portion towards the bottom end portion.

Abstract: An imaging lens assembly includes a plastic barrel and a lens set, and the lens set is disposed in the plastic barrel. The plastic barrel includes an object-side outer surface, a first inner surface and a second inner surface. The lens set has an optical axis, and includes, in order from an object side to an image side thereof, at least one plastic lens element and a spacer. A light-absorbing coating is disposed on the plastic lens element. The spacer includes an object-side connecting surface and a relative surface. When the object-side connecting surface is connected with a neighboring object-side optical element, the relative surface is out of touch with the neighboring object-side optical element. There is an overlap between the second inner surface and the relative surface along a direction parallel to the optical axis.
