優れた効果が得られる。As described above, according to the capacitor manufacturing method according to the present invention, when forming a notch in the resin attached to the lead wire of a capacitor element using a cutter having a pair of blades, the cutter blade is inserted into the lead wire from an obliquely upper direction with respect to the lead wire. After inserting the cutter into the resin adhered to the capacitor, the cutter is rotated downward around the cutting edge to form a notch, so that the cutter blade exerts a force on the resin material that pushes the resin material toward the capacitor element. This provides an excellent effect in that no cracks occur in the resin material of the capacitor element.
