Patent attributes
A multilayer coil component is provided in which solder fusibility and a self-alignment property are prevented from being degraded due to absorption of a flux in a soldering step. The multilayer coil component has no voids present at interfaces between internal conductors 2 and a magnetic ceramic 11 located therearound. A magnetic ceramic forming a central region 7 has a region (side gap portion 8) which extends from a side surface 3a of the magnetic ceramic element to the internal conductors and which has a pore area ratio of 6% to 20%. At least one of a first external layer region 9a, located at an upper side of the central region, and a second external layer region 9b, located at a lower side of the central region (an external layer region at a mounting surface side of a mounting substrate), has a pore area ratio of less than 5%.
