(57) [Summary] [Structure] Cu 5-60ppm, Si 60ppm or less, Fe 60ppm or less and B3 ~ 20ppm, a The ratio of t% B / (at% Ti + at% V) is 5 or more and less than 25, and the Al purity is 99.96% or more. Cu + 1 / More preferably, the amount of 3Zn + 3Ga is 50 to 150 ppm. [Effect] An aluminum foil for an electrolytic capacitor having particularly excellent electrostatic characteristics in a low operating voltage range can be obtained. |
