Abstract:
1. A data communication device comprising: a first electrostatic induction electrode; a second electrostatic induction electrode facing the first electrostatic induction electrode so as to promote electrostatic induction between the first and second electrostatic induction electrodes; a reception and amplification circuit connected to the first electrostatic induction electrode; and a wiring connecting the reception and amplification circuit and the first electrostatic induction electrode, wherein the reception and amplification circuit receives and amplifies an electrostatic induction signal generated at the first electrostatic induction electrode in response to a data signal applied to the second induction electrode, and in plan view of the data communication device, the first electrostatic induction electrode takes a form of an island filled with a conductive material.
