A mechanical keypad with touch panel function includes a key set including a plurality of keycaps and a keytop covering the keycaps, a backlight layer under the key set, a capacitive touch unit selectively disposed under several keycaps, an elastic layer including an elastomer and a plunger corresponding to the keycaps and disposed under the capacitive touch unit as well as a circuit board including metal domes and dome sheets corresponding to the keycaps. Each metal dome provides a mechanical feedback force so that the keycaps are able to be in indirect contact with the metal domes and the dome sheets by means of the plunger.
