Multilayer inductor and multilayer inductor array

A multilayer inductor array comprising:

• an element body including a plurality of magnetic layers laminated in a lamination direction;
• a first external electrode, a second external electrode, a third external electrode, a fourth external electrode, a fifth external electrode, a sixth external electrode, a seventh external electrode, and an eighth external electrode that are on a bottom surface of the element body;
• a first coil including a first winding portion configured by connecting, through a via, end portions of a plurality of first conductors in different layers of the element body, a first through-conductor that connects one end of the first winding portion that is relatively close to the bottom surface and the first external electrode to each other, and a second through-conductor that connects another end of the first winding portion that is relatively away from the bottom surface and the second external electrode to each other;
• a second coil including a second winding portion configured by connecting, through a via, end portions of a plurality of second conductors in different layers of the element body, a third through-conductor that connects one end of the second winding portion that is relatively close to the bottom surface and the third external electrode to each other, and a fourth through-conductor that connects another end of the second winding portion that is relatively away from the bottom surface and the fourth external electrode to each other;
• a third coil including a third winding portion configured by connecting, through a via, end portions of a plurality of third conductors in different layers of the element body, a fifth through-conductor that connects one end of the third winding portion that is relatively close to the bottom surface and the fifth external electrode to each other, and a sixth through-conductor that connects another end of the third winding portion that is relatively away from the bottom surface and the sixth external electrode to each other,
• a fourth coil including a fourth winding portion configured by connecting, through a via, end portions of a plurality of fourth conductors in different layers of the element body, a seventh through-conductor that connects one end of the fourth winding portion that is relatively close to the bottom surface and the seventh external electrode to each other, and an eighth through-conductor that connects another end of the fourth winding portion that is relatively away from the bottom surface and the eight external electrode to each other,
• the third coil and the fourth coil are adjacent to each other in a direction intersecting the lamination direction with respect to the first coil and the second coil,
• a first conductor and a second conductor are in a same layer, the first conductor being one of the plurality of first conductors, the second conductor being one of the plurality of second conductors, and an area of the first conductor in plan view is substantially same to an area of the second conductor in plan view in the same layer,
• the first conductors and the second conductors are alternately disposed in the direction intersecting the lamination direction,
• a third conductor and a fourth conductor are in a same layer, the third conductor being one of the plurality of the third conductors, the fourth conductor being one of the plurality of the fourth conductors, and an area of the third conductor in plan view is substantially same to an area of the fourth conductor in plan view in the same layer, and
• the third conductors and the fourth conductors are alternately disposed in the direction intersecting the lamination direction.
