Abstract
An electronic pen includes an electrically conductive coil spring that expands and contracts, a core body having electrical conductivity, a writing pressure detector having a fitting part fitted to an end of the core body on a side of the core body that is opposite to a side of the core body that includes a pen tip, and an electronic circuit that includes an oscillating circuit. The electronic circuit, in operation, causes a detection result from the writing pressure detector to be included in a signal from the oscillating circuit. The core body penetrates through a center axis of the coil spring and is not biased by the coil spring, and a first end of the coil spring on a side of the coil spring adjacent to the pen tip is connected to the core body and a second end of the coil spring is connected to the electronic circuit.
