  • Patent number: 10496231
    Abstract: A touch panel having a noise guiding member for guiding noise current such as static electricity generated during operating is provided. The noise guiding member is made of a metal material, and is arranged in a position that a front surface side end portion does not project from a front surface of a housing unit. In a state that a back surface side end portion is connected to the ground G, the noise guiding member passes through a back surface from the front surface of the housing unit. The touch panel can reduce manufacturing costs without design restriction, and control adverse effect subjecting by noise current due to external discharge such as static electricity generated when operating the touch panel.
