摘要： An inductor component includes a base made of an insulating material; and a coil disposed in the base and helically wound along an axis. The insulating material contains a base material made of an amorphous material containing B, Si, and O and contains a crystalline filler. The base has a high-concentration-phosphorus-containing portion at a position along the coil, and a concentration of P in the base material in the high-concentration-phosphorus-containing portion is higher than a concentration of P in the base material in a central portion of the base.

摘要： In a coil component, a shield layer is provided after the unevenness of the surface of an element body is smoothened by the surface being covered with an insulating layer. A Cu layer of the shield layer is provided on a smooth surface, and thus a thickness variation can be suppressed and the Cu layer can be formed with a substantially uniform thickness. In the coil component, a point where the shield layer is thin or a point lacking the shield layer is unlikely to be generated and a functional degradation of the shield layer is effectively suppressed.

摘要： A coil component includes an insulator part and a coil part. The insulator part is constituted by an electrical insulation material, and is no more than 600 μm long and no more than 600 μm high. The coil part is wound around one axis and placed inside the insulator part. The coil part has an opening part constituted by straight line parts and curved line parts and whose shape as viewed from the one axis direction is an approximate quadrangle, wherein the line length of the curved line parts along the inner periphery of the opening part is 20% or more but no more than 40% of the line length of the inner periphery of the opening part. The coil component can satisfy both a size reduction need and the properties need.

摘要： 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%).
