Abstract: A wireless power transmission device includes a power feeding unit and a power receiving unit. The power feeding unit and the power receiving unit are disposed so that a principal surface of a primary magnetic core and a principal surface of a secondary magnetic core face each other across a primary winding and a secondary winding. The distance from a surface of a feeding-side shield member which faces a feeding-side coil to a surface of the feeding-side coil which faces the feeding-side shield member, is longer than the distance from a surface of a receiving-side shield member which faces a receiving-side coil to a surface of the receiving-side coil which faces the receiving-side shield member.
