Abstract
A position indicating device includes a variable capacitance capacitor, which has: a first electrode; a second electrode; and a dielectric separating the first electrode and the second electrode. A capacitance of the variable capacitance capacitor varies in response to application of pressure to the variable capacitance capacitor. The position indicating device also includes a core body having a tip including a third electrode, wherein, in operation, a signal is transmitted by the third electrode and pressure applied to the tip of the core body is transmitted to the variable capacitance capacitor, varying the capacitance of the variable capacitance capacitor. The position indicating device also includes a first terminal electrically connected to the first electrode; a second terminal electrically connected to the second electrode; a third terminal; and a core body holder configured to electrically connect the third electrode to the third terminal.
