Since the fine analysis of self-energy problem by Weisskopf, the fact that the electron has finite extension over the region h/mc has been used to calculate the reaction problem. But the positive proof for this conventional model is not yet given. In this paper we shall discuss the explicit form of electron.
By the way, the unique method of separation of self-energy which is independent of the external field applied on the electron will also be given.
