The disclosure provides a charging base. The charging base is applied to electrically connect to an electronic device and charge a stylus. The charging base includes: a base, a connector, a first charging end conductive structure, and a second charging end conductive structure. The base includes a through-hole. The connector is disposed on one side of the base and is used for being electrically connected to the electronic device. The first charging end conductive structure is formed on an upper surface of the base and is electrically connected to the connector. The second charging end conductive structure is formed in the through-hole and is electrically connected to the connector.
