  • Publication number: 20210249189
    Abstract: A method for producing a multilayer coil component includes preparing an insulating sheet; forming a resin paste layer on the insulating sheet by using a resin paste; forming a conductive paste layer by using a conductive paste, the conductive paste layer covering the resin paste layer and having a projecting portion at a portion where a second void portion is to be formed; forming an insulating paste layer on the insulating sheet by using an insulating paste such that at least part of an upper surface of the conductive paste layer is exposed; stacking the insulating sheets having the resin paste layer, the conductive paste layer, and the insulating paste layer formed thereon to form a multilayer compact that includes the conductive paste layers connected into a coil shape; and firing the multilayer compact.

  • Publication number: 20210249178
    Abstract: A highly reliable multilayer coil component, in which the difference in shrinkage ratio between an insulator portion and a conductor portion during firing can be reduced, includes an insulator portion; a coil that is embedded in the insulator portion and includes a plurality of coil conductor layers electrically connected to one another; and outer electrodes that are disposed on surfaces of the insulator portion and are electrically connected to the coil. The coil conductor layers that are adjacent to each other in a stacking direction are connected to each other through a via conductor and a connecting conductor, and the connecting conductor has a pore area ratio smaller than a pore area ratio of the coil conductor layers.

  • Publication number: 20210249172
    Abstract: A highly reliable multilayer coil component in which the internal stress is further alleviated, and a method for producing the same. The method produces a multilayer coil component that includes an insulator portion, a coil that is embedded in the insulator portion and includes a plurality of coil conductor layers electrically connected to one another, and an outer electrode that is disposed on a surface of the insulator portion and is electrically connected to an extended portion of the coil. The method includes forming a conductive paste layer by using a conductive paste; forming an insulating paste layer by using an insulating paste; forming a multilayer compact that includes the conductive paste layer and the insulating paste layer; and firing the multilayer compact, in which the conductive paste has a PVC of 60% or more and 80% or less (i.e., from 60% to 80%).
