The object of the invention is to find a new configuration, a material, and a manufacturing method of an elastomer keypad provided with a pressing element capable of pressing a switch element with less keystroke loss and clear clicking feeling, and further capable of simplifying processes more than insert molding method which uses the conventional pressing element made of a resin (resin chip). Concave portions 71 and 72 for forming silicone resin pressing elements 41 and 42 which are attached to keypads 2 and 21 are provided at predetermined positions in dies 51, 52, 61, and 62 for manufacturing a keypad; the concave portions are filled with a silicone resin 9 to start hardening; and subsequently the dies are supplied with a silicone rubber material to form keypad main bodies 2 and 21, so that keypads 2 and 21 are obtained with the silicone resin pressing elements 41 and 42 being integrated.
