Abstract
A capacitor includes: a cathode foil including a carbon layer disposed at a surface of a base material foil; and a lead-out terminal including a flat portion connected to the cathode foil by stitch connection at a stitch connection portion, and a thickness of the stitch connection portion is equal to or less than a total thickness of a thickness of the cathode foil and a thickness of the flat portion.
Claims20
A capacitor comprising:
- a cathode foil including a carbon layer disposed at a surface of a base material foil;
- and
- a lead-out terminal including a flat portion connected to the cathode foil by stitch connection at a stitch connection portion, wherein
- a thickness of the stitch connection portion is equal to or less than a total thickness of a thickness of the cathode foil and a thickness of the flat portion.
A method for manufacturing a capacitor, the method comprising:
- a step of producing a cathode foil including a carbon layer disposed at a surface of a base material foil;
- and
- a step of disposing a flat portion of a lead-out terminal on a terminal arrangement surface of the cathode foil, and connecting the flat portion to the cathode foil at a stitch connection portion by a stitch connecting process so that a thickness of the stitch connection portion is equal to or less than a total thickness of a thickness of the cathode foil and a thickness of the flat portion.
A method for manufacturing a capacitor, the method comprising:
- a step of grasping a thickness of a cathode foil including a carbon layer disposed at a surface of a base material foil and a thickness of a flat portion of a lead-out terminal;
- a step of determining a thickness of a stitch connection portion so that the thickness of the stitch connection portion is equal to or less than a total thickness of the thickness of the cathode foil and the thickness of the flat portion;
- a step of adjusting a stitch connection device so that the stitch connection device crushes the stitch connection portion until the thickness of the stitch connection portion becomes the determined thickness;
- and
- a step of connecting the flat portion to the cathode foil by the adjusted stitch connection device.
