Abstract
A coil electronic component includes a body and external terminals. The body includes a winding coil part and a pillar-shaped core part inserted inside of the winding coil part and formed of a magnetic metal. The external terminals are connected to the winding coil part and disposed on an external surface of the body. The body contains the magnetic metal and a resin, and the pillar-shaped core part has magnetic permeability higher than that of a portion of the body disposed outside of the winding coil part.

9. A method of manufacturing a coil electronic component, the method comprising:
-
punching a plurality of magnetic sheets to have holes extending therethrough, and stacking the punched magnetic sheets to form first, second, and third blocks each having a respective groove formed therein; inserting a pillar-shaped core formed of a magnetic metal into a groove formed in the first block; stacking the second block having a through hole formed therein on the first block so that the pillar-shaped core is disposed to penetrate through the through hole; loading a winding coil around the pillar-shaped core; and stacking the third block on the second block to form a multilayer body in which the winding coil is loaded so that the pillar-shaped core is positioned in a groove of the third block. - View Dependent Claims (10, 11, 12, 13, 14, 15)

16. A method of manufacturing a coil electronic component, the method comprising:
-
forming a first block from a plurality of magnetic sheets stacked in a thickness direction and comprising a magnetic metal, the first block having a groove extending from an upper surface through a partial thickness thereof; inserting a pillar-shaped core formed of the magnetic metal into the groove formed of the first block; forming a second block from a plurality of magnetic sheets stacked in the thickness direction and comprising the magnetic metal, the second block having a through hole extending through a thickness thereof; stacking the second block on the first block such that the pillar-shaped core extends through the through hole of the second block; disposing a winding coil around the pillar-shaped core within the through-hole of the second block; forming a third block from a plurality of magnetic sheets stacked in the thickness direction and comprising the magnetic metal, the third block having a groove extending from a lower surface through a partial thickness thereof; and stacking the third block on the second block such that the pillar-shaped core extends into the groove of the third block. - View Dependent Claims (17, 18, 19)
