| 摘要 |
The present invention relates to a wireless charging device which includes a magnetic body substrate; a coil part which is formed on the magnetic body substrate and is made with a conductive material; a first connection terminal which touches the outer end of the coil; a connection member which is formed in the lower part of the coil part and has one side electrically connected to the inner end of the coil part; and a second connection terminal which touches the other side of the connection member. The thickness of the connection member is 0.1 to 0.8 times thicker than that of the coil part so that inductance is improved and current resistance is reduced to be slim. |
