Abstract
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.
