By a guide member disposed adjacent to a conductive wire wound in a form of a coil, a magnetic pad according to an embodiment is capable of increasing a transmission rate of an electromagnetic signal generated from the conductive wire. Accordingly, a wireless charging element comprising the magnetic pad may be usefully used in an electric vehicle and the like requiring a large-capacity power transmission between a transmitter and a receiver. The magnetic pad comprises: a magnetic sheet; a conductive wire; and one or more guide members.
구현예에 따른 자성 패드는, 코일 형태로 감긴 도전성 와이어에 인접하여 배치되는 가이드 부재에 의하여, 상기 도전성 와이어에서 발생하는 전자기 신호의 전송율을 높일 수 있다. 따라서 상기 자성 패드를 포함하는 무선 충전 소자는 송신기와 수신기 간의 대용량의 전력 전송을 요구하는 전기 자동차 등에 유용하게 사용될 수 있다.
