Abstract
A lens module with physically stronger foundations and enhanced stability includes a circuit board, an image sensor thereon, a mounting bracket, an optical filter, and a lens unit. The mounting bracket is connected to the surface of the circuit board which has the image sensor. The optical filter is connected to mounting bracket and positioned above the image sensor. The lens unit is connected to the mounting bracket facing away from the circuit board through a frame of adhesive. The surface of the lens unit connected to the mounting bracket has protrusions which are positioned at inner edges of the adhesive layer. The protrusions are taller than the depth of the adhesive layer.
