  • Publication number: 20240103670
    Abstract: A capacitive electronic pen includes a housing, a core body, and a peripheral electrode. In the capacitive electronic pen, the core body includes an electrode core formed of a conductor having a spherical section and a shaft center section. The spherical section of the electrode core is not surrounded by the peripheral electrode and is disposed on a tip (distal) end of the capacitive electronic pen protruding from one opening in the axial direction of the housing. The shaft center section of the electrode core has multiple portions that vary in thickness (a cross-section size) including a thin portion, which coupled with the spherical section, and a thick portion. When the core body is fitted to the core body holder, at least a portion of the shaft center section of the electrode core is thinner than the diameter of the spherical section of the electrode core.
