ABSTRACT:
A condenser and the production method thereof are disclosed, wherein the condenser is composed of a positive foil sheet, a negative foil sheet and an isolating sheet which are placed one on another in combination, a plurality of lead terminals and another plurality of lead terminals, the one plurality of lead terminals being positioned at a circumferentially same phase and arranged in alignment in one radial direction of the cylindrical condenser and the another plurality of lead terminals being positioned at a circumferentially same phase and arranged in alignment in another radial direction of the cylindrical condenser; and wherein the production method is to attach the one and another plurality of lead terminals to the positive foil sheet and the negative foil sheet respectively with a predetermined space provided therebetween, and then roll up the combined sheets by cooperation of a rotational sheet rolling up shaft and a rotational drive roller which is pressed against the circumferentially outer surface of the combined sheets on the sheet rolling up shaft so as to prevent uneven tensions being applied to the combined sheets as the sheets are rolled up.
