ABSTRACT:
Tantalum powder and solid electrolytic capacitor using the same are disclosed. Cohered powder or Low CV powder is added to High CV powder in order to noticeably enhance an anchor effect during molding and therefore to increase the mechanical strength of a molding. Further, the addition of powder cohered beforehand prevents a contraction ratio from increasing at the time of sintering and thereby prevents the cavity distribution of an anode body from increasing, so that the electrical characteristic is improved.
