Nucleation induced by electric field is called the electrical nucleation. A history and a recent development of induction time for the electrical nucleation are reviewed from theoretical and experimental aspects. The induction time is one of information to compare a theory with experiments on nucleation. On the theoretical aspects, Kashchiev's theory is mainly reviewed, where a relation between electric field and free energy of a system is discussed and an equation for induction time depending on electric field is drived. On the experimental aspects, measurements of the induction time of the electrical nucleation are shown for a system of supercooled aqueous solution of a sodium acetate trihydrate. It is shown that the elctric field plays a role of a dryving force of nucleation. Some comparison of the theory with experiments are also shown.
