としての酸化層３を形成する。That is, as shown in FIG. 1, first, a metal wire having a valve action is attached to a capacitor pellet 1 which is made by press-molding a metal powder having a valve action, such as tantalum, niobium, aluminum, etc., into a cylindrical shape and sintering it. was planted as anode lead 2,
An oxide layer 3 as a dielectric layer is formed on this capacitor pellet 1 by chemical conversion treatment.

。However, the anode lead 2 that can be derived from the capacitor pellet 1 has a high melting point (and is difficult to solder).
Difficult to connect to other electrical circuits, capacitor pellet 1
The first external lead wire 8 cannot be directly led out as an external lead wire, and therefore it is necessary to weld the first external lead wire 8 made of an L-shaped metal member that is easy to solder to the anode lead wire 2.
そてコンデンサＡの製作は、単体として行なわれるもの

リード線８の溶接後適当な個所で切断されている。The capacitor A is not manufactured as a single unit (with the anode lead 2 exposed (indicated by a chain line in the drawing), its end is welded to the strip member 9, and a plurality of these are connected together). The most commonly manufactured type is one in which the first external lead wire 8 is welded and then cut at an appropriate location.

重量個所を溶接している。The first external lead wire 8 is welded prior to the soldering of the second external lead wire 6 to the electrode extraction layer 5, and the anode lead 2 and the first external lead wire 8 are welded using a three-pronged jig 10. Intermediate member 1 of jig 10, holding external lead wire 8 of 1
After determining the dimension (A) between both 2 and 8 using 0a, the weight points are welded.

。In this case, dimension A) is set to insert the first and second external lead wires 6 and 8 into the standardized mounting holes of the printed circuit board when capacitor A is mounted on the printed circuit board (not shown). When implanting the anode lead 2 into the capacitor pellet 1, the dimension (0) force between the lead 2 and the electrode extraction layer 5 is determined, so once the dimension (A) is determined, the second external lead wire 6 and the dimension C is determined.

てコンデンサＡの小型化の妨げとなっていた。Therefore, in order to further downsize the capacitor A,
The dimension (A) between the anode lead 2 and the first external lead wire 8 can be made as small as possible, and the component of the resin 7 can be made small. 10a and a pin member as an intermediate member cannot be inserted between the anode lead and the first external lead wires 2 and 8, and the final distance between the first external lead wire 8 and the second external lead wire 6 could not be made constant, and in addition, workability was significantly impaired, which hindered miniaturization of capacitor A.
