A sheet for capacitor electrodes includes an aluminum core sheet 3 and a porous layer 4 formed on at least one surface of the core sheet 3 . The porous layer 4 includes an intermetallic compound made of one or more valve metals selected from the group consisting of Ti, Zr, Nb, Hf and Ta, and Al. The porous layer is constituted such that particles of the intermetallic compound are fixed in solid solution in which the one or more valve metals are dissolved in Al. Atomized molten alloy including valve metal and Al is sprayed approximately downward, and an inert gas flow 19 is injected against the spray flow to generate a branched spray flow 16 of the atomized alloy from the spray flow 15 . The branched spray flow 16 is jetted against a foil-like core material 3 and then rolled. According to the sheet for capacitor electrodes, larger capacitance can be obtained and the sheet is excellent in bent-resistant performance.
