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: In a photosensitive conductive paste containing photosensitive organic components, conductor powder, and quartz powder, melting of the quartz powder does not occur or is very unlikely to occur in a heat treatment step, and in the heat treatment step, it functions sufficiently to bring shrinkage rates and shrinkage behaviors of both of a conductor layer and an element body layer closer to each other when they shrink, and thus generation of voids can be inhibited when it is used for manufacturing a laminated coil component.

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.
