(FR) ÉLÉMENT DE PROTECTION
(JA) カバー部材
Abstract: front page image
(EN)The present invention pertains to a cover member comprising at least glass, the glass Vickers hardness Hv being at least 600, the glass having a first surface and a second surface facing the first surface, and the dielectric constant of the glass at a frequency of 1 MHz being at least 12. This cover member makes a high contribution to improving the sensing sensitivity of a capacitive sensor and has excellent abrasion resistance.
(FR)La présente invention concerne un élément de protection comprenant au moins du verre, la dureté Vickers Hv dudit verre étant d'au moins 600, le verre ayant une première surface et une seconde surface faisant face à la première surface, et la constante diélectrique du verre à une fréquence de 1 MHz étant d'au moins 12. Cet élément de protection contribue grandement à l'amélioration de la sensibilité de détection d'un capteur capacitif et présente une excellente résistance à l'abrasion.
(JA) 本発明は、少なくともガラスを備え、前記ガラスのビッカース硬度Hvが600以上であり、前記ガラスは第1面と前記第1面に対向する第2面を有し、前記ガラスの周波数1MHzにおける比誘電率が12以上であるカバー部材に関する。本発明のカバー部材は、静電容量方式センサーのセンシング感度の向上への寄与が高く、かつ耐擦傷性に優れる。
