Abstract
The segregation in the hydrogen-absorbing alloy is decreased by a centrifugal casting which is devised in the present invention so that: a melt fed to the bottom portion of a cylindrical rotary mold solidifies during one rotation of the mold; and, the average depositing speed of melt is from approximately 0.005 to 0.1 cm/second.
