A touchpad module includes a base plate, a touch member, a switch, an elastic element, a first supporting element and a second supporting element. The base plate includes a triggering part. The touch member is located over the base plate. The switch is disposed on the touch member and aligned with the triggering part. The elastic element is located under the base plate. The elastic element includes a fixed part, a first swingable part and a second swingable part. The fixed part is fixed on the base plate. The first swingable part includes a first contact structure. The second swingable part includes a second contact structure. When an external force is exerted on the touch member, the touch member is swung toward the base plate relative to the first supporting element, and the second swingable part is swung away from the base plate.
