TANTALUM METAL POWDER DISPERSED SOLUTION, ANODE ELEMENT FOR TANTALUM ELECTROLYTIC CAPACITOR, TANTALUM ELECTROLYTIC CAPACITOR USING ANODE ELEMENT AND METHOD OF MANUFACTURING FOR ANODE ELEMENT FOR TANTALUM ELECTROLYTIC CAPACITOR

摘要

PROBLEM TO BE SOLVED: To miniaturize an anode element for a tantalum electrolytic capacitor and increase the electrostatic capacity as electrical characteristics. SOLUTION: In tantalum metal powder dispersed liquid, at least a solvent, a solvent soluble binder resin shown by a general formula (in formula, l, m, n show real numbers having the relation l/2+m+n=100, and R is an alkyl group) and tantalum metal powder are contained. After the tantalum metal powder dispersed solution is spread on a base substance and made a spread object, the anode element for a tantalum electrolytic capacitor is obtained by sintering the spread object.
