Abstract

A solid electrolytic capacitor is made with an Aluminum-titanium body. Aluminum and titanium powders are press-molded into a body which is then heated sufficiently to provide a porous Al-Ti alloy with an oxide layer. Next, the body is heated in an atmosphere containing at least 0.1% by volume of oxygen at a temperature in the range of about 500.degree.-700.degree. C. Thereafter, a layer of manganese dioxide is formed over the oxide layer and a cathode electrode layer is then formed over the manganese dioxide layer.
