A sheet to shield electromagnetic waves for wireless charging, comprising:
- a base part;
- and
- a magnetic material embedded in the base part,
- wherein a density of the magnetic material in a region of the magnetic material corresponding to a shape of a coil of a reception coil member or a transmission coil member and a region of the magnetic material corresponding to an inner side of the coil is higher than a density of the magnetic material in other regions of the magnetic material,
- wherein the coil comprises a spiral shape, and
- wherein a density of the magnetic material in a central region of the magnetic material bounded by a perimeter of a through-hole of the coil is higher than a density of the magnetic material in an outer region of the magnetic material surrounding the central region.
A wireless power reception apparatus, comprising:
- a base part;
