Abstract: A position indicator includes a chassis, a core body, and a variable capacitance capacitor. The capacitor includes a dielectric, a first conductor disposed on a first surface of the dielectric, a first terminal coupled to the first conductor, forming a first electrode, a second conductor disposed on a second surface of the dielectric, an electrically-conductive member disposed opposed to the second surface of the dielectric, a second terminal that forms a second electrode of the capacitor with the second conductor and the electrically-conductive member, and an elastic member. In operation, the elastic member applies a biasing force to separate the electrically-conductive member from the second surface of the dielectric. The electrically-conductive member contacts the second conductor on the second surface of the dielectric in response to the force applied through the core body, and, in response to the contact, a capacitance of the capacitor changes to a determined capacitance.
