Imaging lens assembly module, camera module and electronic device

Abstract

Imaging lens assembly module (100) comprising: a lens assembly (110) with a central axis (X); and an opaque optical element (120) arranged along the central axis (X) with the lens assembly (110) and comprising: a central aperture (121) arranged around the central axis (X); a light-blocking section (122) extending from the central aperture (121) in a direction away from the central axis (X) and pointing towards an object side or an image side of the lens assembly (110); and a plurality of spiral structures (123) arranged on the light-blocking section (122) and around the central axis (X);wherein each of the spiral structures (123) comprises an adaxial end near the central axis (X) and an abaxial end away from the central axis (X), and each of the spiral structures (123) extends spirally from the adaxial end to the abaxial end by orbiting the central axis (X) in a direction away from the central axis (X).
