1. An electronic device comprising:
a protection panel including a decoration layer having a transparent window section;
a casing including a panel fitting section having an opening, said protection panel being fitted into said panel fitting section such that outer surfaces of said protection panel and said casing are flush with each other; and
a display device on a lower side of said protection panel and arranged so as to be visually recognizable from an outside of said electronic device through said transparent window section of said protection panel;
wherein said protection panel further includes:
a transparent protection panel main body having an upper surface with a transparent lower electrode thereon and a lower circuit arranged around said transparent lower electrode so as to be covered by said decoration layer, and having a lower surface with a notch therein for accommodating a circuit sheet connected to said lower circuit such that said circuit sheet accommodated within said notch is covered by said decoration layer;
a movable electrode film including a transparent resin film having a lower surface with a transparent upper electrode located opposite to said transparent lower electrode and an upper circuit arranged around said transparent upper electrode so as to be covered by said decoration layer, said movable electrode film having peripheral portions bonded to said transparent protection panel main body such that an air layer is formed between said movable electrode film and an upper side of said protection panel main body; and
a transparent resin cover film on an upper surface of said transparent resin film of said movable electrode film, said decoration layer being formed on at least one surface of said transparent resin cover film.
