Abstract: In a coil 5 of a multilayer coil component 1, an end portion 6a of a turn 6 closest to a side surface 2e in the facing direction of the side surface 2e and a side surface 2f is connected to a first external electrode 3 and an end portion 11a of a turn 11 closest to the side surface 2f in the facing direction of the pair of side surfaces 2e and 2f is connected to a second external electrode 4. The area at which the turn 6 faces the second external electrode 4 and the area at which the turn 11 faces the first external electrode 3 are smaller than the area at which turns 7, 8, 9, and 10 other than the turn 6 and the turn 11 face the first external electrode 3 or the second external electrode 4.

Abstract: A multilayer coil component includes an element body, a coil, and a pair of terminal electrodes. Each of the pair of terminal electrodes is formed by a plurality of electrode layers having different shapes being stacked in a stacking direction and is exposed on end surfaces, a main surface, and a pair of side surfaces. One electrode part of the terminal electrodes exposed on the side surfaces of the element body and formed by one of the electrode layers has an overlapping part overlapping at least a part of the other electrode part formed by another of the electrode layers adjacent to the one electrode layer in the stacking direction and a non-overlapping part not overlapping the other electrode part when viewed from the stacking direction.

Abstract: A laminated electronic component includes an element body and a pair of conductors. The element body is formed by laminating a plurality of element-body layers in a first direction. The pair of conductors is formed by laminating a plurality of conductor layers in the first direction. The pair of conductors is provided to the element body in such a way as to be separated from each other in a second direction orthogonal to the first direction. At a cross section orthogonal to the first direction, the pair of conductors has an uneven portion and the element body has an uneven portion engaged with the uneven portion of the pair of conductors.

Abstract: A multilayer coil component includes an element assembly that has a first surface and second surfaces extending in a direction orthogonal to the first surface, and terminal electrodes that has first electrode parts extending in a direction orthogonal to the first surface along the second surfaces. At least a portion of the first electrode parts of the terminal electrodes is disposed inside the element assembly. The element assembly is present between imaginary lines extending in a direction parallel to the first surface toward the second surfaces from a position farthest from the first surface in a direction orthogonal to the first surface in the first electrode parts positioned inside the element assembly and the first surface.
