で、正確に折り曲げることができる。[Function] The vertical aluminum electrolytic chip capacitor, which is a single product with the electrolytic capacitor body and the insulating plate stable, is mounted on a board with an electric circuit using a self-inserting machine. The pressed lead rod moves on the insulating plate without shifting the position of the electrode without gripping even when gripping the insulating plate part, and it can be stably and accurately placed on the electrode of the substrate . Also, when pressing the lead rod flat, instead of pressing the lead rod after inserting it into the insulating plate as in the past, it is possible to press it cleanly on the part close to the sealing part, and it is also thin when bending. Since the pressed portion is bent, it can be bent accurately.

The aluminum electrolytic capacitor 1 having the lead rod 2 is positioned between the center mold 5 and the side mold 6 and pressed, and the lead rod 2 is pressed as shown in FIGS.
Is flattened. Then, as shown in FIG. 1 (c), after inserting the lead lead rod into the through hole of the insulating plate 3, the flat portion 4 is bent along the insulating plate 3 as shown in FIG. And the insulating plate 3 are fixed.
