1. A multilayer coil component comprising:
an insulator portion;
a coil that is embedded in the insulator portion and includes a plurality of coil conductor layers electrically connected to one another, conductive portions of the coil conductor layers having a pore area ratio of 5% or more and 15% or less; and
outer electrodes that are disposed on surfaces of the insulator portion and are electrically connected to extended portions of the coil,
wherein the coil is electrically connected to the outer electrodes through the extended portions, and the extended portions include conductive low pore area ratio layers that have a smaller pore area ratio than the conductive portions of the coil conductor layers.
