Solid electrolytic capacitor and method for manufacturing same

A solid electrolytic capacitor comprising:

• at least one porous sintered body having a pair of main faces opposed to each other, a pair of side faces opposed to each other, and a pair of end faces opposed to each other;
• a metal lead partly embedded in the at least one porous sintered body, the metal lead extending from one of the pair of main faces;
• a dielectric layer disposed on a surface of the at least one porous sintered body;
• a solid electrolyte layer disposed on the dielectric layer;
• a first terminal electrically connected to the metal lead;
• and
• a second terminal electrically connected to the solid electrolyte layer, wherein:
• the first terminal includes a first terminal mounting part and a standing part having a slot, the first terminal mounting part extending in substantially parallel to each of the pair of side faces, the slot extending in substantially parallel to each of the pair of main faces,
• the second terminal includes a terminal connecting part and a second terminal mounting part, the terminal connecting part being electrically connected to the solid electrolyte layer, the second terminal mounting part extending in substantially parallel to each of the pair of side faces, and
• the metal lead is electrically connected to each of a pair of connection surfaces of the slot, the pair of connection surfaces being opposed to each other.

A method for manufacturing a solid electrolytic capacitor, the method comprising:

• forming a capacitor element including at least one porous sintered body, a metal lead partly embedded in the at least one porous sintered body, a dielectric layer disposed on a surface of the at least one porous sintered body, and a solid electrolyte layer disposed on the dielectric layer, the at least one porous sintered body having a pair of main faces opposed to each other, a pair of side faces opposed to each other, and a pair of end faces opposed to each other, the metal lead extending from one of the pair of main faces;
• forming a first terminal metal plate and a second terminal metal plate from a single metal plate;
• forming a first terminal from the first terminal metal plate, the first terminal including a first terminal mounting part, a pair of arm parts opposed to each other, and a bent part disposed between the first terminal mounting part and the pair of arm parts, the first terminal mounting part extending in substantially parallel to each of the pair of side faces, the pair of arm parts extending in substantially parallel to each of the pair of end faces;
• forming a second terminal from the second terminal metal plate, the second terminal including a terminal connecting part and a second terminal mounting part, the terminal connecting part being electrically connected to the solid electrolyte layer, the second terminal mounting part extending in substantially parallel to each of the pair of side faces;
• and
• electrically connecting the metal lead to each of the pair of arm parts in a state where the metal lead is sandwiched between the pair of arm parts.
