wherein the electronic component has a trench formed in one side thereof.

2. The electronic component package of claim 1 , wherein the trench is confined by protrusion parts protruding from a body of the electronic component, and

the body and protrusion parts are an integral portion and are made of a same material.

3. The electronic component package of claim 1 , wherein the electronic component has a plurality of protrusion parts formed on the one side thereof adjacently to the trench.

4. The electronic component package of claim 3 , wherein the protrusion part has a square pillar shape, a rectangular pillar shape, or a cylindrical pillar shape.

5. The electronic component package of claim 1 , wherein the trench of the electronic component is filled with the encapsulant.

6. The electronic component package of claim 5 , wherein a coefficient of thermal expansion (CTE) of the electronic component is less than that of the encapsulant filled in the trench of the electronic component.

7. The electronic component package of claim 1 , wherein the encapsulant is a solid material.

8. The electronic component package of claim 1 , wherein the electrode component is an integrated circuit having an electrode pad formed on the other side thereof, and

the electrode pad of the integrated circuit is oriented toward the redistribution layer.

9. The electronic component package of claim 1 , further comprising another metal layer disposed on a wall of the trench of the electronic component.

10. The electronic component package of claim 1 , further comprising:

a through-wiring penetrating through the frame; and

wiring patterns disposed on both surfaces of the frame opposing each other.

11. The electronic component package of claim 10 , further comprising insulating layers disposed on both surfaces of the frame opposing each other,

wherein one of the insulating layers has openings exposing the wiring patterns.

12. The electronic component package of claim 1 , further comprising:

an outer layer disposed on one side of the redistribution layer and having openings; and

connection terminals disposed in the openings.

13. An electronic component package comprising:

a redistribution layer;

an electronic component disposed on the redistribution layer and including a body and protrusion parts protruding from the body;

a metal layer including a plurality of sections respectively disposed on side surfaces of the protrusion parts; and

an encapsulant encapsulating the electronic component and filling spaces between the plurality of sections of the metal layer.

14. The electronic component package of claim 13 , wherein the body and the protrusion parts are an integral portion and are made of a same material.

15. The electronic component package of claim 13 , wherein a coefficient of thermal expansion (CTE) of the electronic component is less than that of the encapsulant filled between the plurality of sections of the metal layer.

16. The electronic component package of claim 13 , wherein the encapsulant is a solid material.

17. The electronic component package of claim 13 , wherein the electrode component is an integrated circuit having an electrode pad one side of the electronic component opposing the protrusion parts, and

the electrode pad of the integrated circuit is oriented toward the redistribution layer.

18. The electronic component package of claim 13 , further comprising a frame disposed on the redistribution layer and having a through-hole,

wherein the electronic component is disposed in the through-hole, and

the encapsulant fills a space, between the electronic component and the frame, of through-hole.

19. The electronic component package of claim 18 , further comprising:

a through-wiring penetrating through the frame; and

wiring patterns disposed on both surfaces of the frame opposing each other.

20. The electronic component package of claim 13 , further comprising:
