An electronic pen includes a conductive core-side member, a power supply circuit, a signal transmission circuit, an input reception circuit, and a control circuit. The signal transmission circuit receives a power supply voltage from the power supply circuit, generates a first signal and a second signal each having a different waveform, and selectively supplies either the first signal or the second signal to the core-side member. The input reception circuit which receives a designation input designating either the first signal or the second signal to be supplied from the signal transmission circuit to the core-side member. The control circuit controls the signal transmission circuit to supply either the first signal or the second signal to the core-side member according to the designation input received by the input reception circuit.
