According to an embodiment of the disclosure, as illustrated in FIG. 2A, an electronic pen 220 may be attached to a rear surface of the electronic device 210. A groove is formed on the rear surface of the electronic device 210 so that a user may insert the electronic pen 220 into the groove of the electronic device 210 to store the electronic pen or may use the electronic pen 220 while the electronic pen is inserted into the groove of the electronic device 210. According to an embodiment of the disclosure, as illustrated in FIG. 2B, an electronic pen 240 may be attached to a side surface of an electronic device 230. A user may attach the electronic pen 240 to the side surface of the electronic device 230 to store the electronic pen and may use the electronic pen while the electronic pen is attached to the side surface of the electronic device 230. The disclosure is described with a foldable electronic device as an example in FIG. 2, but may also be applied to different types of electronic devices, such as a bar-type electronic device, and a rollable electronic device. The thickness of the electronic device may be reduced when the electronic pen is not inserted into the electronic device and is attached to one side of the exterior thereof as described herein. As the electronic pen is attached to one side of the exterior of the electronic device, a user can easily attach or detach the electronic pen. According to various embodiments of the disclosure, when the electronic pen includes a hardware component, such as a button and a sensor, the electronic pen may share or replace some functions of the electronic device.
