Abstract
In a multilayer coil component, a part filled with a resin and a void part not filled with the resin exist between a plurality of metal magnetic particles in an element body, one main surface of the element body is a mounting surface with respect to an external electronic component, and the edge of an external electrode is positioned on the mounting surface. In the element body, a high void region where the porosity caused by the void part is higher than the porosity of the other part in the element body extends from the edge of the external electrode on the mounting surface toward an end surface of the element body.
