    Abstract: A multilayer coil component includes an element body, first and second coils, and a pair of external electrodes. The element body includes a plurality of insulator layers laminated in a first direction. The element body has a pair of end surfaces opposing each other in a second direction orthogonal to the first direction. The first coil and the second coil are disposed in the element body and respectively have coil shafts along the second direction. The pair of external electrodes are disposed on the pair of end surfaces and electrically connected to both ends of the first coil and the second coil. The first coil includes a first conductor layer, a second conductor layer, and a first through hole conductor. The coil shaft of the first coil is disposed inside the second coil.

    Abstract: A method for manufacturing an electronic-component includes a step of forming a laminate substrate including a plurality of laminates disposed in a direction intersecting with a lamination direction via a division portion by laminating a plurality of insulator layers, and a step of singulating the plurality of laminates by removing the division portion. The step of forming the laminate substrate includes a step of forming an insulator resist layer containing an insulating material on a base material, the insulating material being a constituent material of each of the insulator layers and a step of forming the insulator layer by curing the insulator resist layer by exposure, except for at least an insulator resist portion corresponding to the division portion. The division portion including the insulator resist portion is removed by development in the step of singulating.

    Abstract: In a stepwise structure formed in a multilayer coil component, a difference occurs in a shrinkage amount between a maximum film thickness portion in which the number of layers is large and a minimum film thickness portion in which the number of layers is small due to portions different in the number of layers of coil parts (that is, upper coil part, lower coil part, and connecting part) adjacent to each other like the maximum film thickness portion and the minimum film thickness portion, readily causing a crack by an inner stress due to the difference in the shrinkage amount. In a multilayer coil component according to the present disclosure, a stress relaxation part overlapping with a maximum film thickness portion whose shrinkage amount is large is provided to relax inner stress in a stepwise structure, resulting in prevention of a crack.

    Abstract: A method of manufacturing a laminated coil component is a method of manufacturing a laminated coil component provided with a laminate obtained by laminating a coil conductor forming a spiral coil and an insulator layer. The method of manufacturing a laminated coil component includes a step of providing a conductor pattern configured to become a coil conductor on a green sheet configured to become an insulator layer, and a step of laminating a plurality of green sheets provided with the conductor pattern. The conductor pattern includes a pair of first side surfaces opposed to each other in an orthogonal direction orthogonal to a laminating direction of the green sheet. At the step of laminating a plurality of green sheets, a depression is formed on at least one of the pair of first side surfaces.

    Abstract: A multilayer coil component includes an element body and a plurality of coil conductors. The element body includes a plurality of metal magnetic particles and resin existing between the plurality of metal magnetic particles. The plurality of coil conductors is disposed in the element body, the plurality of coil conductors being separated from each other in a predetermined direction and electrically connected to each other. The plurality of metal magnetic particles included in the element body includes a plurality of metal magnetic particles having a particle size equal to or greater than one third of a distance between the coil conductors adjacent to each other in the predetermined direction and equal to or less than a half of the distance. Between the coil conductors adjacent to each other in the predetermined direction, the metal magnetic particles having the particle size are distributed along the predetermined direction.
