Zusammenfassung:	The present application relates to a boron compound in the form of fine particles characterized by being obtainable by dissolving one or more boron compounds selected from (1) to (3) described below in an aromatic hydrocarbon solvent and then precipitating in an aliphatic hydrocarbon solvent: (1) a boron compound represented by the general formula: BQ1Q2Q3, (2) a boron compound represented by the general formula: G+(BQ1Q2Q3Q4)-, and (3) a boron compound represented by the general formula: (L-H)+(BQ1Q2Q3Q4)- (in each of the above general formulae, B is a boron atom in the trivalent valence state, Q1 to Q4 are a halogen atom, a hydrocarbon group, a halogenated hydrocarbon group, a substituted silyl group, an alkoxy group or a di-substituted amino group, which may be the same or different, respectively. G+ is an inorganic or organic cation, L is a neutral Lewis base, and (L-H)+ is a Brønsted acid).
