Patent ID: 8587565

Claim:
A position indicator comprising: a substantially elongated case; a rod partially housed in the case and having a first end protruding outside the case and a second end extending inside the case; and a variable capacitor housed inside the case and configured to change its capacitance when an external force is applied through the rod to the variable capacitor, wherein the variable capacitor includes: at least one dielectric having a first surface and a second surface opposite the first surface; an electrode provided in a defined shape to cover a first defined area on the first surface of the dielectric; a conductive member attached to the second end of the rod such that it faces the second surface of the dielectric; and a conductive portion having a defined width and a defined length to cover a second defined area on the second surface of the dielectric, the second defined area being less than half the first defined area and the conductive portion being electrically connectable to the conductive member, wherein the conductive member is configured to be elastically deformed when pressed against the second surface of the dielectric by the external force applied through the rod, such that the capacitance of the variable capacitor changes according to a change of the external force, and wherein no area of the electrode provided on the first surface of the dielectric overlaps with the conductive portion provided on the second surface of the dielectric in a direction in which they oppose each other.
