Zusammenfassung:	PURPOSE:To produce a polysiloxane oligomer reduced in impurities, having a long pot life and useful for a film-forming composition. CONSTITUTION:This polysiloxane oligomer is produced by reacting metal silicon with an alcohol to synthesize a tetraalkoxysilane and conducting a hydrolytic dehydration polycondensation of the resultant tetraalkoxysilane. In this polysiloxane oligomer, the content of chlorine is
