A position indicator includes a time-constant circuit having an element whose characteristic continuously varies in response to operation represented as a continuous quantity such as writing force, and capable of switching the variation range of time constant in response to the variation in characteristic of the element in at least two ways; and a discharging/charging device capable of discharging the time-constant circuit from a predetermined voltage to a voltage below a specified voltage, or charging the time-constant circuit from the predetermined voltage to a voltage exceeding the specified voltage. Using the time-constant circuit and discharging/charging device, the number of waves of AC signals at a specified frequency is counted from the discharge start time to the time when the voltage falls below the specified voltage, or from the charge start time to the time when the voltage exceeds the specified voltage, by switching the variation range of time constant.
