An electromagnetic induction type connection terminal for charging a battery includes a charging paddle and a charging receptacle for receiving the charging paddle. The charging paddle has a primary coil that is connected to a power supply station. The charging receptacle has a secondary coil that is connected to the battery. A current sent from the power supply station is supplied to the primary coil, which causes a current to flow the secondary coil. The charging paddle includes a paddle case having a surface, which has an opening, a protrusion extending from the paddle case, and a core about which the primary coil is wound. The core is held within the paddle case, and surfaces of the core are exposed through the opening. The protrusion is positioned near the exposed surfaces of the core for preventing the exposed surfaces of the core from being damaged when the charging paddle is plugged into the charging receptacle.
