Abstract: A solid electrolytic capacitor includes a capacitor element and a resin package enclosing the capacitor element. Two anode leads, partially enclosed by the package, are connected to the opposite ends of the anode bar that are allowed to protrude in the opposite directions from an anode chip of the capacitor element. The capacitor element is provided with a cathode layer connected to an external cathode electrode arranged between the paired anode leads. With this symmetrical structure of two anode leads and one cathode electrode, the solid electrolytic capacitor can be mounted onto a printed circuit board without worrying about the polarity of the capacitor. Further, the proximity of the cathode electrode and the respective anode leads serves to reduce the self-induction in a high-frequency range.

Abstract: An anode lead (11) is embedded at one end thereof in a sintered body in a capacitor element (1), and is welded at the other end thereof to a first outside lead (2). A cathode (12) is electrically connected to a second outside lead (3). The capacitor element is covered with a resin, thereby forming a resin package (5). The tip end of the first outside lead, to which the other end of the anode lead 11 is welded, is configured in such a manner as to have a capacity greater than those of other portions of the first outside lead: namely, the tip end of the first outside lead is widened or thickened in such a manner as to increase the volume of the first outside lead per unit length. Thus, it is possible to provide a solid electrolytic capacitor having the structure in which inclination of the welded portion of the anode lead can be eliminated or the welding reliability of the anode lead can be enhanced without reducing the size of the sintered body in the capacitor element or increasing the size of the package.

A concave is formed in one end surface of a porous chip formed by hardening metal powder and a synthetic resin is filled in the concave. An anode bar is provided which passes through the synthetic resin to be fixed to the chip. After a dielectric film is formed on the surface of the chip through anodic oxidation, a solid state electrolytic layer made of manganese dioxide is formed on the dielectric film and then, a cathode film is formed thereon. At an end surface of the chip, an insulating film is provided, so that the distance between the lead terminal and the chip is reduced without any short circuit being caused.
