An embodiment relates to an assembled pad assembly characterized by comprising: a reception pad supporting a reception coil; the reception coil connected to the outside by a wire and positioned on the reception pad; and a magnetic composite layer disposed above or below the reception coil, wherein the amount of increase in inductance of the pad assembly after assembly relative to before assembly is 25 (%·cm3/g) or more per unit density of the magnetic composite layer. According to the embodiment, wireless charging with excellent charging efficiency is possible for electric transportation means, etc., and excellent charging efficiency can be well maintained even when an impact or repeated vibration is applied to the pad assembly. La présente invention concerne, selon un mode de réalisation, un ensemble tampon assemblé caractérisé en ce qu'il comprend : un tampon de réception supportant une bobine de réception ; la bobine de réception étant connectée à l'extérieur par un fil et positionnée sur le tampon de réception ; et une couche composite magnétique disposée au-dessus ou au-dessous de la bobine de réception, l'augmentation de l'inductance de l'ensemble tampon après assemblage par rapport à avant assemblage étant de 25 (%-cm3/g) ou plus par unité de densité de la couche composite magnétique. Selon le mode de réalisation, une charge sans fil avec une excellente efficacité de charge est possible pour les moyens de transport électriques, etc., et l'excellente efficacité de charge peut être bien maintenue même lorsqu'un choc ou une vibration répétée est appliqué à l'ensemble tampon. 구현예는 수신코일을 지지하는 수신패드; 외부와 와이어로 연결되며 상기 수신패드 상에 위치하는 수신코일; 그리고 상기 수신코일의 위 또는 아래에 배치되는 자성복합체층;을 포함하는 조립된 패드조립체로, 조립 전을 기준으로 하는 조립 후의 상기 패드조립체의 인덕턴스 증가량은 상기 자성복합체층의 단위밀도당 25 (%·cm3/g) 이상인 것을 특징으로 한다. 구현예에 따르면, 전동 이동수단 등에 우수한 충전효율로 무선충전을 가능하게 하며 패드조립체에 충격이나 반복적인 진동이 가해져도 우수한 충전효율이 잘 유지될 수 있다.
