Electronic pen

An electronic pen comprising:

• a cylindrical chassis;
• a circuit board disposed within a pillar-shaped hollow portion of the chassis, the circuit board having a planar surface that extends in an axial direction of the hollow portion of the chassis;
• and
• a connector disposed within the pillar-shaped hollow portion of the cylindrical chassis, the connector being exposable from a first opening in an axial direction of the chassis to outside of the chassis and adapted to be coupled to a mating connector inserted from a direction along the axial direction of the chassis,
• wherein the connector includes a housing having a contact portion and a base portion coupled to each other in the axial direction of the chassis, and a shell covering at least the base portion of the housing,
• wherein the contact portion of the connector has a planar surface that extends in the axial direction of the chassis, and a plurality of contact conductors configured to be electrically connected to the mating connector is formed on the planar surface,
• wherein the shell has a first size in a direction parallel to the planar surface of the contact portion and orthogonal to the axial direction of the chassis that is smaller than a diameter of the hollow portion of the chassis,
• wherein the shell of the connector is coupled to the circuit board in a state in which the direction of the first size of the shell is parallel to the planar surface of the circuit board, and in a state in which a width of the circuit board in a direction orthogonal to an axial direction of the circuit board is less than the first size of the shell, and
• wherein the shell includes a conductor that is coupled to the circuit board and electrically connects the shell to a reference electric potential of the circuit board.
