Abstract: A position indicator includes a capacitor having a capacitance that changes in correspondence to a force applied to one end part of a housing. The capacitor is configured by a pressure detecting chip that includes a first electrode and a second electrode disposed opposite to the first electrode with a predetermined distance defined therebetween to have capacitance Cv formed between the first electrode and the second electrode. The capacitance Cv changes when the force applied to the one end part of the housing is transmitted to the first electrode to thereby change a relationship (e.g., the distance) between the two electrodes. A pressure transmitting member having predetermined elasticity is disposed on the first electrode such that the force applied to the one end part of the housing is transmitted to the first electrode of the semiconductor element via the pressure transmitting member.
