The present invention aims to provide a method of producing a hydrogen absorbing alloy electrode which is solid and enables a metal hydride storage cell, using the hydrogen absorbing alloy electrode, with high discharge characteristics in high-rate discharge and in low temperature and a long cycle life. To achieve this, the hydrogen absorbing alloy electrode is produced by firstly generating a first powder by giving a surface treatment to a hydrogen absorbing alloy powder in an acid solution, secondly generating a mixed material by mixing the first powder with a second powder which is composed of a metal which does not absorb hydrogen and/or an alloy which does not absorb hydrogen, thirdly attaching the mixed material to a base plate, and fourthly baking the base plate for sintering the mixed material attached to the base plate. The hydrogen absorbing alloy electrode may also be produced by firstly generating a first powder by attaching a nickel-rich metal to the surface of a hydrogen absorbing alloy powder, secondly generating a mixed material by mixing the first powder with a second powder which is composed of a metal which does not absorb hydrogen and/or an alloy which does not absorb hydrogen, thirdly attaching the mixed material to a base plate, and fourthly baking the base plate for sintering the mixed material attached to the base plate.
