Disclosed is lens module. The lens module includes a barrel and a lens group disposed in the barrel. The lens group includes a first lens element connecting with the barrel and a second lens element connecting with the first lens element. The first lens element connecting with the barrel makes the lens module have a first matching precision. The first matching precision makes the barrel and the lens group be concentric. The first lens element has a first arc surface and the second lens element has a second arc surface engaging with the first arc surface which makes the lens module have a second matching precision. The second matching precision makes the first lens element and the second lens element be concentric.
