Abstract: In a laminated inductor element, a magnetic ferrite layer sandwiched between two conductor patterns is thinner than other magnetic ferrite layers. Therefore, a crack occurs in the magnetic ferrite layer due to firing. As a result of the occurrence of this crack, a stress applied to each layer is relaxed, and it becomes possible to avoid warpage, a crack, or the like. In addition, in the laminated type inductor element, the two conductor patterns are electrically connected by two via holes, and subjected to a same potential. Since the two conductor patterns correspond to a same wiring pattern and a coil of coil conductor is defined by the two conductor patterns, even if upper and lower coil conductors are electrically in contact with each other due to the crack, the two conductor patterns are not put into a short-circuited state.

Abstract: A multilayer inductor device in which parasitic inductance is made smaller while preventing increase in a mounting area of the device and complexity of a wiring pattern, and a manufacturing method of the stated multilayer inductor device. An outer electrode and a terminal electrode are connected to each other through a via hole. A side surface of a non-magnetic member forms a part of an end surface of the device, while the other side surface thereof being in contact with the via hole.

Abstract: In a laminated inductor element, outer electrodes and terminal electrodes are electrically connected by via holes, internal wiring lines, and end surface electrodes. The via holes on an upper surface side are provided immediately under the outer electrodes and in a non-magnetic ferrite layer. The via holes on a lower surface side are provided immediately above the terminal electrodes and in a non-magnetic ferrite layer. Since outermost layers are defined by the non-magnetic ferrite layers, a parasitic inductance is not increased, even if the outermost layers are provided with the via holes. In this case, the internal wiring lines are not routed on a surface of the element. Therefore, there is no complication of a wiring pattern, and it is possible to prevent an increase in a mounting area of the element.

Abstract: In a laminated coil component include coil conductors are respectively included on magnetic layers and a carbon paste is included on a magnetic layer. The coil conductors include a partial coil conductor and a partial coil conductor respectively corresponding to an outer side portion circle and an inner side portion circle defining two circles. A width of the carbon paste at least partially overlaps an interval between the outer side portion circle and the inner side portion circle defining the two circles, and extends circularly along the two circles. The carbon paste is shifted to the interval between the outer side portion circle and the inner side portion circle defining the two circles at the time of pressure-bonding the magnetic layers. The carbon paste vanishes when being calcined to define an air gap.
