In a pressure sensor, a pressure-sensitive layer faces a first electrode pattern and a second electrode pattern with a space interposed therebetween. The first electrode pattern includes a plurality of first electrode sections, a first interconnecting section that interconnects the plurality of first electrode sections, and a first wiring section that extends from a first end of the first interconnecting section. The second electrode pattern includes a plurality of second electrode sections disposed alternately with the first electrode sections, a second interconnecting section that interconnects the plurality of second electrode sections, and a second wiring section that extends from a second end of the second interconnecting section. The second wiring section extends such that the resistance of the conduction path between an output terminal of the first wiring section and an output terminal of the second wiring section is substantially the same for any adjacent pairs of the first electrode sections and the second electrode sections when the first electrode section and the second electrode section conduct with each other via the pressure-sensitive layer.

Pressure sensor

A pressure sensor is disclosed. The pressure sensor includes a common electrode, a plurality of individual electrodes, a plurality of thin-film transistors and a common pressure-sensitive layer. The common electrode is formed as a layer. The plurality of individual electrodes are arranged in a matrix opposing the common electrode. The plurality of thin-film transistors are respectively located corresponding to the individual electrodes on sides of the individual electrodes opposite to the common electrode, where one or two or more adjacent thin-film transistors are connected to one individual electrode. The common pressure-sensitive layer is disposed on a surface of the common electrode on a side facing the plurality of individual electrodes. The plurality of individual electrodes include a first electrode, and a second electrode that is thicker than the first electrode and therefore creates a smaller gap from the common pressure-sensitive layer than the first electrode.

A resistive film type touch panel is configured to reduce damage that is caused by contact between electrodes in a resistive film type touch panel that includes a plurality of first electrodes and a plurality of second electrodes that extend in direction that intersect one another. The resistive film type touch panel includes a plurality of lower side electrodes and a plurality of upper side electrodes. The lower side electrode extends in the Y direction. The upper side electrode Xextends in the X direction, which intersects the Y direction, and opposes the plurality of lower side electrodes. Each lower side electrode includes an electrically conductive layer and protective layers, and a silver layer and a carbon layer extend in the Y direction. The protective layers are formed on edge parts on both sides in the width direction of the electrically conductive layer such that they extend in the direction.
