A remote controller includes a case having an upper surface having an opening provided therein, an electrostatic touch panel provided at the opening of the case, a board having an upper surface facing the electrostatic touch panel, a push switch provided on upper surface of the board, a cover sheet provided on the upper surface of the board, a control section operable to detect a position on the upper surface of the electrostatic touch panel where the user touches, and a transmitter to send a remote signal in response to the detected position and an activation of the push switch. The electrostatic touch panel can move toward and away from the circuit board. The cover sheet has a deformable projection projecting. The deformable projection has an upper tip contacting the electrostatic touch panel. The deformable projection has substantially a dome shape having a concave lower surface and a convex upper surface.
