ダクタンス素子を得る。 In FIG. 2, reference numeral 11 denotes a long winding core used in the present invention, which is made of a magnetic material such as ferrite, an insulating material such as alumina, etc., and has a plurality of transverse grooves 12 at predetermined intervals on one surface. It has been established that Such a winding core 11 can be obtained by forming transverse grooves at the same time as molding, or by not forming transverse grooves during molding and then forming transverse grooves by cutting. In the manufacturing method of the present invention, first, electrodes 13 are formed on the surface of the winding core 11 on which the transverse grooves 12 are provided, excluding the transverse grooves.
form. This electrode 13 is made of a conductive film,
It is formed by an appropriate means such as screen printing and baking, and is shown applied to the entire surface except for the transverse groove in the illustration, but it may be applied to at least part of both sides of each transverse groove. Next, the conductive wire 14 is wound a predetermined number of times in the transverse groove portion on the A side of one end of the winding core 11 to form a coil, and the winding end 15 is extended into the adjacent transverse groove along the surface of the electrode 13. A coil is also formed in the transverse groove portion. In this way, the conductive wire 14 is sequentially wound up to the transverse groove portion on the other end B side of the winding core 11, thereby continuously forming a coil. At this time, if a linear groove is provided at the upper end corner of each transverse groove of the winding core 11 and the conductive wire is passed through this portion, the position of the conductive wire is fixed and the winding work becomes more stable. Be able to do it. Next, a conductive wire provided along the surface of the electrode 13 is connected and fixed to the electrode portion.
This connection and fixation is accomplished by appropriate means such as dipping the electrode surface into molten solder and soldering, or welding. Finally, the winding core 1 is connected to the dot-dashed line shown in FIG.
1 is cut with a diamond cutter or the like in a direction intersecting its longitudinal direction to obtain individual chip-shaped inductance elements.
