2. Description of the Related Art In the production of an electronic component having an electronic component lead wire, for example, an electrolytic capacitor, a flat plate portion formed on the electronic component lead wire is passed through an aluminum foil while supplying the electronic component lead wire. It is fixed and manufactured.

In the above-described manufacturing process, it is necessary to supply the flat plate portion in parallel with the aluminum foil. Conventionally, the flat plate portion was sandwiched so that the rotation direction of the flat plate portion was aligned in a fixed direction. Since the rotation direction of the flat plate portion was aligned by simply holding the flat plate portion, if the flat plate portion was supplied in an upright state, the flat plate portion was deformed by being crushed by the holding member, sometimes making it impossible to perform boring processing In some cases, the flat plate portion is damaged, the electrical performance of the manufactured electrolytic capacitor is degraded, and the lead wires of the electronic components are not fixed to the aluminum foil and are defective.
