1. A board provided for wireless charging and near field communication, comprising:

a first polymeric film;

a soft magnetic layer provided on the first polymeric film;

a second polymeric film provided on the soft magnetic layer; and

a coil unit provided on the second polymeric film,

wherein the coil unit includes a first antenna including a plurality of turns and a second antenna including a plurality of turns and provided outside of the first antenna,

wherein the first polymeric film includes a plurality of holes including a first hole and a second hole and a first extending portion that extends further in a first direction than an outermost side of the soft magnetic layer,

wherein the second polymeric film includes a plurality of holes including a third hole and a fourth hole and a second extending portion that extends further in the first direction than the outermost side of the soft magnetic layer,

wherein the first hole and the second hole are disposed inside the second antenna,

wherein the first hole and the third hole are disposed at positions corresponding to each other,

wherein the second hole and the fourth hole are disposed at positions corresponding to each other, and

wherein a lead frame is disposed to protrude more outward than an outermost turn of the second antenna.

2. The board of claim 1 ,

wherein a connected region is formed by the first extending portion and the second extending portion connected to each other,

wherein the connected region is spaced apart from the outermost side and is extended further in an outside direction of the outermost side, and

wherein the first hole and the second hole are spaced apart from each other.

3. The board of claim 2 , wherein the first antenna is disposed between the first hole and the second hole.

4. The board of claim 3 , wherein the first antenna includes a wireless charging antenna.

5. The board of claim 4 , wherein the first hole and the second hole are disposed outside the first antenna.

6. The board of claim 5 , wherein the first hole and the second hole are disposed outside an outermost turn of the first antenna.

7. The board of claim 6 , wherein the innermost turn of the first antenna is disposed on a virtual line connecting a center of the first hole and a center of the second hole.

8. The board of claim 4 , wherein at least one of the first hole or the second hole is disposed between the outermost turn of the second antenna and an outermost turn of the first antenna.

9. The board of claim 4 , wherein a length (l) of at least one of the first extending portion or the second extending portion and a thickness (h) of the soft magnetic layer have a relation of a following equation, wherein A represents a constant of 0.6 to 10:

l=A×h   [Equation]

10. The board of claim 1 , wherein the soft magnetic layer includes a first soft magnetic layer and a second soft magnetic layer.

11. The board of claim 10 , wherein the second soft magnetic layer is disposed on a side of the first soft magnetic layer.

12. The board of claim 10 , wherein the second soft magnetic layer is disposed on the first soft magnetic layer.

13. The board of claim 1 , wherein the soft magnetic layer includes at least one of Fe, Ni, Co, Mn, Al, Zn, Cu, Ba, Ti, Sn, Sr, P, B, N, C, W, Cr, Bi, Li, Y or Cd.

14. The board of claim 13 , wherein at least one of the first polymeric film or the second polymeric film includes at least one of polyethylene, polyacrylic, polyimide, polyamide, or polyurethane.

15. The board of claim 1 , wherein at least one of the first hole or the second hole is a hole for alignment upon manufacturing the board.
