Abstract
A solid electrolytic capacitor is provided that includes a capacitor element having a dielectric coating, a solid electrolyte, and a cathode lead portion formed in order on a surface of an anode portion having an anode lead portion. The cathode lead portion is electrically connected to a cathode terminal by a connecting portion, and the connecting portion is formed of a sintered body of a metal.
Claims6
A method of manufacturing a solid electrolytic capacitor comprising a capacitor element including a dielectric coating, a solid electrolyte, and a cathode lead portion formed in order on a surface of an anode portion having an anode lead portion, the method comprising the steps of:
- superposing a connecting member and a cathode terminal in this order on a surface of said cathode lead portion to form a laminated body;
- and
- heating said laminated body,
- said connecting member being formed of metal nanoparticles and a solvent, and
- said heating step removing said solvent and sintering said metal nanoparticles to form a sintered body which fixes said cathode lead portion and said cathode terminal to each other.
A method of manufacturing a solid electrolytic capacitor comprising a plurality of capacitor elements each including a dielectric coating, a solid electrolyte, and a cathode lead portion formed in order on a surface of an anode portion having an anode lead portion, said plurality of capacitor elements being superposed on each other, the method comprising the steps of:
- superposing a connecting member and a cathode terminal in this order on a surface of the cathode lead portion of at least one capacitor element of said plurality of capacitor elements to form a laminated body;
- and
- heating said laminated body,
- said connecting member being formed of metal nanoparticles and a solvent, and
- said heating step removing said solvent and sintering said metal nanoparticles to form a sintered body which fixes said cathode lead portion and said cathode terminal to each other.
A method of manufacturing a solid electrolytic capacitor comprising a plurality of capacitor elements each including a dielectric coating, a solid electrolyte, and a cathode lead portion formed in order on a surface of an anode portion having an anode lead portion, said plurality of capacitor elements being superposed on each other, the method comprising the steps of:
- superposing, on a surface of the cathode lead portion of one capacitor element of said plurality of capacitor elements, a connecting member and the cathode lead portion of another capacitor element in this order to form a laminated body;
- and
- heating said laminated body,
- said connecting member being formed of metal nanoparticles and a solvent, and
- said heating step removing said solvent and sintering said metal nanoparticles to form a sintered body which fixes the cathode lead portion of said one capacitor element and the cathode lead portion of said another capacitor element to each other.
