  • Electrostatic capacitance-type input device
    Patent number: 9971460
    Abstract: An electrostatic capacitance-type input device includes a first member made of a non-conductive resin, a second member formed together with the first member and made of a conductive resin, a determination unit configured to determine the presence or absence of an input operation of an operator for the second member, based on a change in electrostatic capacitance of the second member, a circuit substrate in which the determination unit is mounted, the circuit substrate being fixed to an inner side portion of a cover member, and a conductive elastic member configured to lie between the second member and the circuit substrate and maintain an electrical connection between the second member and the circuit substrate using an elastic force.
    Type: Grant
