An electrolytic capacitor has a capacitor element formed by winding an anode foil and a cathode foil to which lead terminals are attached, with a separator sandwiched between them. The lead terminal used for this is made of a rod-shaped body made of aluminum, for example, with one end pressed into a flat part, and a lead wire attached to the other end of the rod-shaped body, and an electrode is attached to the flat part. I am trying to attach foil. In that case, in order to control quality, it is necessary to keep the attachment position of the electrode foil relative to the flat part constant.

However, according to this method, when winding up the electrode foil 3, the separator (not shown) may ride on the tapered hem, or the mold may come into contact with the tapered hem during the caulking operation, so this is not preferable. I can't say it's a method. Therefore, as shown in FIG. 6, it is preferable to separate the edge of the electrode foil 3 from the boundary portion by a certain distance L, but in this case, conventionally, the electrode foil 3 is It was necessary to use a caliper or the like to determine whether or not it was fixed in the correct position, which required a considerable amount of time and effort.

In this way, the electrode foils 3, 3 for the anode and the cathode are prepared, and then an electrolytic capacitor is manufactured by a known method.
That is, each electrode foil 3, 3 is wound to a predetermined diameter with a separator (not shown) in between. Next, a rubber sealing body is attached to each lead wire 13 of the lead terminal 10, and after this wound body is impregnated with an electrolytic solution, it is stored in a metal case, and its opening is sealed by caulking or the like. .
