A coil component includes: a body; a coil portion disposed in the body and including a lead-out pattern exposed on one end surface of the body; an insulating layer disposed on the one end surface of the body and having an opening disposed on the lead-out pattern; an external electrode including a connection portion, disposed to be in contact with the lead-out pattern, and a pad portion extending from the connection portion to one surface of the body; and a cover insulating layer disposed on the one end surface of the body to cover the connection portion. The connection portion is spaced apart from all corner portions of the one end surface of the body, except for a corner portion between the one end surface of the body and one surface of the body, on the one end surface of the body.

Coil component

A coil electronic component includes a support substrate having a thickness of 20 to 40 μm. A coil pattern is disposed on at least one of a first surface and a second surface of the support substrate opposing each other, and has an aspect ratio of 4 or higher. An encapsulant encapsulates at least portions of the support substrate and the coil pattern, and an external electrode is disposed in an external region of the encapsulant and connected to the coil pattern.

Coil electronic component

A coil electronic component includes a support substrate, a coil portion disposed on at least one surface of the support substrate, a body in which the support substrate and the coil portion are embedded, and first and second external electrodes disposed on a surface of the body and connected to both ends of the coil portion, respectively. A thickness of the body is 0.55 mm or less. The body includes a cover portion disposed on the coil portion. A ratio of a thickness of the coil portion to a thickness of the cover portion is 5:5 to 8:2.

A coil component includes: a body including a support member including a through-hole, a first insulating layer supported by the support member and including a first opening portion, a second insulating layer disposed on the first insulating layer and including a second opening portion, and a coil including a coil pattern filled in the first and second opening portions; and external electrodes disposed on an outer surface of the body.

An inductor includes: a body including a support member including a through-hole and a via hole, an insulator disposed on the support member and including a first opening exposing portions of the support member, and a coil pattern disposed in the first opening, and including a plurality of layers including a seed layer in contact with the support member; and an external electrode disposed on an external surface of the body and electrically connected to the coil pattern. The support member may have a multilayer structure of at least first and second insulating layers, and the via hole may penetrate through both of the first and second insulating layers.

Inductor and method of manufacturing the same
