Abstract
A solid electrolytic capacitor (A1) includes a first and a second porous sintered bodies (1). Each sintered body (1) is flat, with its thickness being small relative to the width or the length. The first and the second sintered bodies (1) are spaced from each other in the widthwise or lengthwise direction.
Claims25
A solid electrolytic capacitor comprising:
- a first porous sintered body made of a valve metal;
- and
- a second porous sintered body made of a valve metal;
- wherein each of the sintered bodies is flat and includes two principal surfaces;
- and
- wherein the first sintered body and the second sintered body are spaced from each other in a predetermined direction perpendicular to a direction in which the two principal surfaces are spaced from each other.

A method of manufacturing a solid electrolytic capacitor, the method comprising the steps of:
- compacting valve metal powder to form a porous compact;
- positioning the porous compact on a metal plate with a bonding material containing valve metal powder;
- and
- fixing the porous compact to the metal plate by sintering.
1 more element
A solid electrolytic capacitor comprising:
- a porous sintered body formed by sintering a compact made of valve metal powder;
- a metal plate supporting the porous sintered body;
- and
- a bonding material provided between the porous sintered body and the metal plate for fixing the porous sintered body to the metal plate;
- wherein the bonding material is obtained by heating a paste containing valve metal powder having a particle diameter smaller than that of the powder used for forming the compact.
