Touch panel board with guard portion and flexible wiring board connecting guard portion to ground wire

摘要

A touch panel board includes an electrode board, a cover panel, a flexible wiring board, a guard portion, and a ground connection wire. The electrode board includes a support board, sensor electrodes supported on the support board, and connection terminals electrically connected to the sensor electrodes and supported on the support board and collectively arranged on an outer side with respect to the sensor electrodes. The flexible wiring board includes conductive wires, one end thereof being connected to the connection terminals, respectively, and a ground wire. The conductive guard portion is arranged on a side of the opposing surface of the projected end portion to be arranged on an outer side with respect to the connection terminals. The ground connection wire electrically connects the guard portion and the ground wire.
