Abstract: In a coil component includes an insulating layer interposed between an external terminal and an element body and formed in an entire region excluding a connection region in a formation region in which the external terminal is formed, even when a high transient voltage is applied between the pair of external terminals, insulation breakdown does not occur or hardly occurs because of the insulating layer.

Abstract: In the coil component, the external terminal and the metal magnetic powder-containing resin constituting the element body are not in direct contact with each other, and thus high ESD resistance is obtained. That is, even when a high transient voltage is applied between the pair of external terminals, insulation breakdown is less likely to occur, and an improvement in breakdown voltage with respect to the transient voltage can be realized.
