[Problem] To provide a method for manufacturing a tab terminal for an electrolytic capacitor, the method enabling the suppression of the occurrence of whiskers and causing no problem in an environment aspect after welding. [Solution] A method for manufacturing a tab terminal for an electrolytic capacitor comprises: joining one end of an aluminum core wire and one end of a lead wire by welding to form a joined body; cleaning the joined body in a cleaning tank; coating a welded portion of the cleaned joined body with an ultraviolet curable resin composition; and irradiating the coated portion with ultraviolet rays to create a coating produced from ultraviolet curable resin, and is characterized in that in the cleaning tank, a cleaning solution circulates via a magnetic filter, and an alloy or an intermetallic compound of Fe and metal selected from a group consisting of Cu, Sn, Al, Bi, and Ni, which was generated by cleaning the joined body, is removed by the magnetic filter. |
