Abstract
In a coil component, a second magnetic portion disposed in the vicinity of a coil is designed to have a higher proportion of Fe than a metal magnetic powder-containing resin constituting a first magnetic portion. Therefore, a magnetic flux of the coil flows smoothly. Although the second magnetic portion has a relatively lower withstand voltage than the first magnetic portion, since the second magnetic portion is surrounded by the first magnetic portion, it is not exposed on an outer surface of a magnetic body. For this reason, a situation in which the coil and external terminal electrodes are short-circuited with the second magnetic portion therebetween is effectively curbed, and short-circuiting between the coil and the external terminal electrodes can be curbed.
