Abstract
(EN)
The present disclosure addresses the problem of providing: a touch sensor which has improved detection accuracy of touch operations; and a wiring apparatus. A touch sensor according to the present invention is provided with a substrate (30), a sensor electrode (31) and a first ground electrode (32). The substrate (30) comprises a first layer (L1) and a second layer (L2). The sensor electrode (31) is formed in the first layer (L1). The first ground electrode (32) is formed in the second layer (L2) such that at least a part thereof overlaps with the sensor electrode (31) in the thickness direction of the substrate (30); and a parasitic capacitance is formed between the first ground electrode (32) and the sensor electrode (31). At least one of the sensor electrode (31) and the first ground electrode (32) comprises a plurality of through holes (320) which are formed within a region where the sensor electrode (31) and the first ground electrode (32) overlap with each other in the thickness direction of the substrate (30).

La présente invention aborde le problème consistant à fournir : un capteur tactile qui a une précision de détection améliorée d'opérations tactiles ; et un appareil de câblage. Le capteur tactile selon la présente invention comporte un substrat (30), une électrode de capteur (31) et une première électrode de masse (32). Le substrat (30) comprend une première couche (L1) et une seconde couche (L2). L'électrode de capteur (31) est formée dans la première couche (L1). La première électrode de masse (32) est formée dans la seconde couche (L2) de telle sorte qu'au moins une partie de celle-ci chevauche l'électrode de capteur (31) dans la direction de l'épaisseur du substrat (30) ; et une capacité parasite est formée entre la première électrode de masse (32) et l'électrode de capteur (31). Au moins l'une de l'électrode de capteur (31) et de la première électrode de masse (32) comprend une pluralité de trous traversants (320) qui sont formés dans une région où l'électrode de capteur (31) et la première électrode de masse (32) se chevauchent dans la direction de l'épaisseur du substrat (30).
