An electronic pen has a cylindrical chassis, a circuit board disposed within a pillar-shaped hollow portion of the chassis, and a connector exposable from an opening in the chassis to outside of the chassis. The connector includes a housing and a shell. The shell has a first size in a direction parallel to a planar surface of a contact portion of the connector and orthogonal to the axial direction of the chassis that is smaller than a diameter of the hollow portion of the chassis. The shell is coupled to the circuit board in a state in which the direction of the first size of the shell is parallel to a planar surface of the circuit board, and a width of the circuit board in a direction orthogonal to the axial direction of the circuit board is less than the first size of the shell.
