发明名称 Laminated inductor
摘要 A laminated inductor includes: a laminate having an insulating part constituted by non-magnetic layers, as well as a coil part constituted by conductors positioned between the non-magnetic layers; and external electrodes that are electrically connected to the ends of the coil part and positioned on the exterior surfaces of the laminate; wherein the external electrodes each have a first electrode layer whose primary constituent is Ag, as well as a second electrode layer whose primary constituent is Cu and which is positioned on the outer side of the first electrode layer and has a thickness of 4 μm or more, and the total thickness of the first electrode layer and second electrode layer is 5 μm or more and preferably 10 μm or less.
