METHOD OF MANUFACTURING LEAD FRAME FOR CAPACITORS, AND LEAD FRAME FOR CAPACITORS

摘要

PROBLEM TO BE SOLVED: To make it possible to set the thickness of a thin plate portion to a predetermined thickness or less and set the width of a thick plate portion to a predetermined width or less and apply a material having high hardness. SOLUTION: There is provided a method of manufacturing a lead frame for capacitors in which a capacitor element including a positive electrode lead line protruded from the side surface and a negative electrode exposed to the side surface is built. A metal plate section and a cutting member are transferred relatively along the longitudinal direction of the metal plate section while pressing the cutting member against a portion of the principal surface of the planar metal plate section and a thick plate portion which is connected to the positive electrode lead line and a thin plate portion which is connected to the negative electrode are formed.
