Abstract
PURPOSE:To form a titanium film having coarse prismatic structure, to impregnate a capacitor element with paste up to details and to obtain a large-capacitance aluminium electrolytic capacitor by using an aluminum cathode foil in which titanium is evaporated onto an aluminum foil substrate in an argon gas atmosphere, the degree of vacuum of which is kept within a specific range. CONSTITUTION:A capacitor element on which an aluminum cathode foil, in which titanium is evaporated onto an aluminum foil substrate 2 in an argon gas atmosphere, the degree of vacuum of which is kept within a range of 1.0X10<-5>-10X10<-4>Torr, and an aluminum anode foil are wound through a separator is impregnated with an electrolytic solution for drive. Evaporation is conducted generally at the high degree of vacuum in order to improve adhesive properties and shape a dense film, but evaporation is performed at the low degree of vacuum as mentioned above inversely in order to form capacitance in this case, a section between an evaporating source and the evaporating substrate 2 is brought to a low vacuum by gas molecules 3, and titanium is made to collide with gas molecules 3 before titanium reaches the evaporating substrate 2 to deposit on it kinetic energy is reduced, thus acquiring coarse film structure as shown in the figure.
