Abstract: We adopt a semi- classical model and study the potential distribution of a one-dim mesoscopic tunnel junction array when there are many excess electrons in it. We show that there exist multi- charge solitons in one-dim array of mesoscopic tunnel junctions. The main feature of a multi- charge soliton is that its potential peak splits into many peaks. Each island that contains an excess electron corresponds to a potential peak. Meanwhile, we find that the single charge soliton equivalent is also applicable in dealing with multi- charge solitons.

Key words: multi-charge soliton, mesoscopic junction, effective charge, single charge soliton equivalent
