Estimating the term…
The present invention relates to a solid electrolytic capacitor comprising a solid electrolyte layer and an electrically conducting layer comprising metallic powder or an electrically conducting layer comprising an electrically conducting carbon layer and a layer formed thereon and comprising metallic powder in which at least one of said layers contains a rubber-like elastic material; a production process thereof; a solid electrolyte for use in the solid electrolytic capacitor; a production process of the solid electrolyte; an electrically conducting paste for use in the solid electrolytic capacitor; and an electrically carbon conducting paste for use in the solid electrolytic capacitor. The solid electrolytic capacitor of the present invention can be made compact and can be endowed with high-capacitance and low-impedance and is excellent in external force-relaxing properties, productivity, heat resistance and moisture resistance, etc.
An electrically conducting carbon paste for solid electrolytic capacitors comprising an electrically conducting carbon material, a binder, and a solvent, wherein the conducting carbon material contains artificial graphite in an amount of 80 mass % or more, and the artificial graphite has a fixed carbon content of 97 mass % or more, has an average particle size of 1-13 μm, an aspect ratio of 10 or less, and contains particles having a particle size of 32 μm or more in an amount of 12 mass % or less, wherein the binder is a material of rubber-like elasticity which is swellable or suspendable in a solvent.
