摘要:
A position pointer is disclosed, including a housing, a substantially bar-like rod accommodated in the housing such that one end thereof projects to the outer side of the housing, and a variable capacitor having a capacitance value which varies in response to external force applied thereto through the rod. The variable capacitor includes a dielectric member having a first face portion and a second face portion opposite from the first face portion, a terminal member configured to engage with the first face portion of the dielectric member, an electrode section disposed in an opposing relationship to the second face portion of the dielectric member and including a conductive member having a contact area with the second face portion that varies in response to the external force, and an elastic member configured to bias the conductive member in a direction in which the conductive member is spaced away from the second face portion.
