A new form of solutions to some ultradiscrete soliton equations are presented recently. It is called ultradiscrete permanent, which is defined by ultradiscretizing the permanent, that is, signature-free determinant. In this talk, we show properties and relations of the ultradiscrete permanents. Moreover, we prove ultradiscrete soliton solutions by means of an ultradiscrete analogue of Pl\"ucker relation.
