Capacitive input device
First Claim
1. An input device comprising a sensor board, an Xelectrode layer having electrodes, a Y electrode layer having electrodes, andan insulating film disposed between the X and Y electrode;
- anda control circuit board,wherein the X and Y electrode layers are disposed proximate to each other and on one surface side of the sensor board, and the sensor board and the control circuit board bonded to each other by a heated, pressurized thermosetting adhesive such that ends of the electrodes in the X and Y electrode layers on the sensor board contact a conductor portion on the control circuit board.

Abstract
An X electrode layer having X electrodes and a Y electrode layer having Y electrodes are formed on one side of a film board through an insulating film so that the X electrodes and the Y electrodes are arranged into a matrix. Ends of the X electrodes are led to the edge of the film board. The Y electrodes are led through through-holes formed in the insulating film to the edge of the film board in the same plane as the X electrode layer. The X and Y electrodes led to the edge of the film board are connected to a conductor portion formed on a control circuit board. The X and Y electrodes are bonded to the conductor portion by an insulating adhesive containing no conductive particles by heating and pressurization.
