Abstract: A waterproof keypad module, comprising a waterproof film (7) which is in a pre-tightened state and which isolates a touch component from a bottom casing (4); an edge of said waterproof film being fixed at the position where a front casing (1) and the bottom casing (4) connect, and said touch component being supported on said waterproof film (7). The edge of said waterproof film is fixed at the position where the front casing (1) and bottom casing (4) connect, wherein the touch component may be completely isolated from the bottom casing (4) by means of the waterproof film (7); thus, even if a gap exists between the touch component and casing, water cannot pass through the waterproof film (7) and enter the bottom casing (4), thus achieving waterproofing of the keypad module.
