摘要： 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.

摘要： A stretchable mounting board that includes a stretchable substrate having a main surface, a stretchable wiring disposed on the main surface of the stretchable substrate, a mounting electrode section electrically connected to the stretchable wiring, solder electrically connected to the mounting electrode section and including bismuth and tin, and an electronic component electrically connected to the mounting electrode section with the solder interposed therebetween. The mounting electrode section has a first electrode layer on a side thereof facing the stretchable wiring and which includes bismuth and tin, and a second electrode layer on a side thereof facing the solder and which includes bismuth and tin. A concentration of the bismuth in the first electrode layer is lower than a concentration of the bismuth in the second electrode layer, and the concentration of the bismuth in the second electrode layer is constant along a thickness direction thereof.

摘要： A multilayer coil component includes coil conductors including silver planar conductors and ferrite layers containing copper and stacked with the coil conductors and the planar conductors interposed therebetween. The coil conductors define a portion of a coil with a winding axis extending in a lamination direction. The planar conductors are arranged in the lamination direction at a position on an upper side of the coil so that each of principal surfaces thereof faces in the lamination direction and a specific region of the principal surface overlaps with the coil when viewed from the lamination direction. Each of the planar conductors includes first through holes penetrating the principal surface in the lamination direction in the specific region.
