An electrically conductive polymer composition contains an electrically conductive polymer obtained by using a polymer in the form of cations composed of repeating structural units of 3,4-ethylene dioxythiophene and polystyrene sulfonic acid as anions and further contains naphthalene sulfonic acid as an additive. A solid electrolytic capacitor 101 or a surface-mount transmission line element 102 has a polypyrrole conductive polymer layer 3 as a first solid electrolyte and a poly(3,4-ethylene dioxythiophene) conductive polymer layer 4 as a second solid electrolyte.

A surface-mounting thin type capacitor includes a capacitor element having a shape of and two end portions which form a side surface of the capacitor element. Two anode terminals are disposed on lower surfaces of the end portions along the side surface to form a mounting surface substantially perpendicular to the side surface. A cathode terminal is disposed at a middle part of the capacitor element to form the mounting surface together with the anode terminals. The cathode terminal is not between the anode terminals spatially and thereby manufacturing process of the capacitor is simplified and it is easy to change the intended use of the capacitor.

A surface-mount capacitor includes a multilayer capacitor structure formed by laminating plate-like capacitor elements each having anode lead portions at opposite ends thereof and a cathode portion at the center, an anode terminal connected to each anode lead portion via a strip-like plate, and a cathode terminal connected to the cathode portion. The anode and the cathode terminals and have a flat shape and are formed on a common plane as a substrate-mounted surface. A mold resin case has a bottom portion filling a gap between the anode and the cathode terminals and mechanically connecting the anode and the cathode terminals and sidewalls substantially perpendicular to the substrate-mounted surface. The anode and the cathode terminals have upper surfaces exposed on an inner bottom surface of the mold resin case to be connected to the anode lead portions and the cathode portion.

摘要:
A solid electrolytic capacitor is disclosed which combines low LC with Low ESR and which has good characteristics even in a high frequency range, and a method for preparing the same is also disclosed. In the solid electrolytic capacitor whose electrolytic layer contains electrically conductive particles, non-conductive particles are present in at least a part of an interface between a dielectric layer and the electrolyte layer. By employing the structure, local intensifications of field strength in the dielectric layer are prevented to enable a problem of increase in LC to be overcome while keeping ESR low. By the method which comprised a step of applying a colloidal dispersion containing the non-conductive particles in the form of colloidal particles to the post-electrolytic layer formation step product, the solid electrolytic capacitor having the above-mentioned structure can be prepared efficiently.
