An electronic pent includes a case, a core body, and a signal generation circuit. The core body is attached inside the case such that a front end portion in an axial direction protrudes from an opening portion of the case. The signal generation circuit generates a signal to be transmitted from the core body. The core body includes a core rod and a protection member that covers a pen tip portion and an axis portion of the core rod. The core body is provided with a middle portion with a dielectric constant different from a dielectric constant of the protection member, the middle portion being provided around a side surface of the axis portion of the core rod such that the core rod is separated from the protection member.
