Embodiment 1
[0110] (1) A ferrite raw material (calcinated powder) having a predetermined composition is prepared.
[0111] (2) Put the organic binder (polyvinyl butyral resin), organic solvent (ethanol and toluene) into the pot mill together with PSZ balls, and fully mix and pulverize the above calcined powder in wet mode to produce Magnetic slurry.
[0112] (3) The above-mentioned magnetic substance slurry was formed into a sheet shape by a doctor blade method, and punched into a rectangular shape, thereby producing a plurality of magnetic substance sheets with a thickness of 15 μm.
[0113] (4) A conductive paste for an internal conductor including Ag powder and an organic vehicle is prepared.
[0114] (5) By making the via hole in the sheet
[0115] A predetermined position of the magnetic sheet is irradiated with laser light to form a via hole. The via hole conductor is formed by filling the via hole with conductive paste and screen printing the conductive paste in a circular shape...

Abstract
The present invention provides a laminated coil component excellent in high-frequency characteristics. The laminated coil component of the present invention includes: a laminate in which a plurality of insulating layers is laminated and a coil is built in; and a first external electrode and a second external electrode electrically connected to the coil. The coil described above is formed by electrically connecting a plurality of coil conductors laminated together with insulating layers. The laminated coil component of the present invention further includes a first connecting conductor and a second connecting conductor inside the laminated body. The first connecting conductor linearly connects the portion of the first external electrode covering the first end face of the laminate to the coil conductor facing the first external electrode, and the second connecting conductor linearly connects the second external electrode. A portion of the electrode covering the second end face of the laminate is connected to the coil conductor facing the second external electrode. Both the first connection conductor and the second connection conductor overlap the coil conductor and are positioned closer to the mounting surface side than the central axis of the coil when viewed in plan from the stacking direction.
Description
technical field [0001] The present invention relates to a laminated coil component. Background technique [0002] As a laminated coil component, for example, Patent Document 1 discloses a laminated inductor including: a patch having a laminated structure in which a coil is embedded; External terminal electrodes. The multilayer inductor described in Patent Document 1 is characterized in that a lead-out layer having a lead-out inner conductor formed on a layer different from the winding layer having the inner conductor forming the coil in the above-mentioned laminated structure is provided, The surface of the patch that is almost parallel to the winding centerline of the above-mentioned coil is exposed and connected to the end of the above-mentioned coil, and the above-mentioned external terminal electrode is formed on a surface that is almost parallel to the winding centerline of the above-mentioned coil and connected to the above-mentioned lead-out inner conductor. connect...
