Abstract:
PROBLEM TO BE SOLVED: To provide a touch panel used for various kinds of electronic equipment, and a movable contact point body and a switch using the touch panel, which are inexpensively manufactured and securely operated. SOLUTION: A plurality of substantially belt-like lower electrodes 12 formed on an upper surface of a light transmissive lower base sheet 1, and a plurality of substantially belt-like upper electrodes 14 formed in the orthogonal direction to the lower electrodes 12 with a predetermined gap from these lower electrodes 12, are formed of a light transmissive conductive resin, whereby since the lower electrodes 12 and the upper electrodes 14 can be formed by a simple method such as printing, the easily manufacturable and inexpensive touch panel 16 can be provided.

Abstract:
PURPOSE: A keypad in a portable phone and a method for manufacturing the same are provided to present a portable phone keypad that emits fragrance constantly and emits light for itself. CONSTITUTION: A keypad(100) comprises an instrumental material(101), identification codes(103), and a coating layer(105). The identification codes(103) are printed on the protruded portions of the instrumental material(101). The coating layer(105) are coated on the instrumental material(101). The coating layer(105) consists of a lower coating layer(105a) and an upper coating layer(105b). The lower coating layer(105a) is coated by silicon coating, and the upper coating layer(105b) is coated by urethane coating. Also the coating layer(105) comprises directional powders(107a,107b). The directional powders(107a,107b) are contained in either the lower coating layer(105a) or the upper coating layer(105b) or both of them.
