Coil component

A coil component, comprising:

• a body including a magnetic metal powder;
• an internal insulating layer buried in the body;
• an internal coil portion disposed on the internal insulating layer, and including a first conductive layer having turns being in contact with the internal insulating layer, a second conductive layer disposed on the first conductive layer, and a seed layer disposed between the first conductive layer and the second conductive layer, and between a side surface of the internal insulating layer and the second conductive layer;
• an external insulating layer covering the internal coil portion;
• an external coil portion disposed on the external insulating layer and having a greater number of turns than a number of turns of the internal coil portion;
• a connection via penetrating through the external insulating layer and connecting the internal coil portion and the external coil portion;
• and
• an insulating film surrounding the internal insulating layer, the internal coil portion, the external insulating layer, and the external coil portion.

A coil component, comprising:

• an internal insulating layer;
• an internal coil portion having a first number of turns disposed on a first surface of the internal insulating layer, the internal coil portion having a decreasing cross-sectional area in a direction away from the first surface internal coil portion, the internal coil portion comprising at least three layers;
• an external insulating layer covering the internal coil portion;
• an external coil portion having a second number of turns disposed on the external insulating layer, the second number being greater than the first number;
• a through-via penetrating through the internal insulating layer and comprising at least two of the at least three layers of the internal coil portion;
• and
• a connection via penetrating the external insulating layer and connecting the internal coil portion to the external coil portion.
