PROBLEM TO BE SOLVED: To provide an input panel, which can not only sense a touch action provided, when a user inputs an instruction, but also provide the user with a touch-sensing similar to the sensing of pressing the button, such that the user can confirm whether the action of inputting the instruction is finished. SOLUTION: An input panel 300 for a portable electronic device including a switch sheet 320, a touch-sensing sheet 310 and an interposing sheet 330 is provided. The switch sheet includes a circuit board 322 and at least one dome switch 324. The circuit board has at least one contact pad 3222, and the dome switch is disposed on the contact pad. The touch-sensing sheet is disposed on the switch sheet for sensing touch action. The interposing sheet is disposed between the switch sheet and the touch-sensing sheet. The touch-sensing sheet contacts the dome switch, when the touch-sensing sheet is pressed so that the dome switch is deformed elastically to switch on the contact pad. COPYRIGHT: (C)2009,JPO&INPIT
