Abstract: A planar lens (100) and a manufacturing method for a planar lens (100) relate to the technical field of lenses, the planar lens (100) being a focusing lens and comprising an acoustic soft material tangible structure (110) and a cover layer (120), the acoustic soft material tangible structure (110) comprises a plurality of combination lenses (130) located in the same plane, each combination lens (130) comprises a circular part (131) and a plurality of concentric annular parts (132) which are continuously arranged around the circular part (131), the thicknesses of each two adjacent annular parts (132) in each combination lens (130) are different, and the thickness of each annular part (132) is related to the focal length of the respective combination lens (130); and the cover layer (120) covers the outer surface of the acoustic soft material tangible structure (110) to form the planar lens (100).
