TANTALUM CAPACITOR, AND MANUFACTURING METHOD OF TANTALUM CAPACITOR

摘要

PPROBLEM TO BE SOLVED: To provide: a small tantalum capacitor suppressing complication of a manufacturing process and excelling in high-frequency performance; and a manufacturing method of the tantalum capacitor. PSOLUTION: This tantalum capacitor includes: a plurality of tantalum sintered bodies in which first surfaces of the respective tantalum sintered bodies form the same surface, and the respective tantalum sintered bodies are arranged by being spaced apart from each other; a plurality of electrode rods projecting from the first surfaces of the respective tantalum sintered bodies; layers consisting of an oxide film layer, a functional polymer layer or a manganese layer, and a carbon layer which are sequentially laminated on surfaces of the plurality of tantalum sintered bodies excluding the first surfaces; a conductive layer which covers outside surfaces of the plurality of tantalum sintered bodies excluding the first surfaces; and an electrode plate having openings respectively formed at positions facing the respective first surfaces of the plurality of tantalum sintered bodies for exposing the electrode rods therethrough, and connected to the conductive layer by spreading across the first surfaces of the plurality of tantalum sintered bodies.
