Abstract
A variable capacitor of a position indicator includes a dielectric, an electrode, a conductive member and a conductive portion. The dielectric has an upper surface and a lower surface opposite the upper surface. The electrode is provided on the upper surface of the dielectric. The conductive member is arranged so as to face the lower surface of the dielectric. The conductive portion is provided on the lower surface of the dielectric and is arranged so as to be electrically connectable to the conductive member. The conductive member is adapted to be elastically deformed when pressed against the lower surface by an external force, such that the capacitance of the variable capacitor changes according to a change of the external force.
