Claims

[Claims for Utility Model Registration] A character sheet made of a flexible film that forms a keypad portion on which letters or numbers are written, and an adhesive that has an opening corresponding to the keypad portion formed on a current-carrying plate. a first pattern and a second pattern interposed between the substrate and the character sheet, which contact the current-carrying plate of the substrate and become electrically conductive when the keypad section is pressed; What is claimed is: 1. A key unit comprising a conductive pattern consisting of a pattern and a conductive pattern consisting of a visible film having insulating properties disposed on the back surface thereof.
