A method for preparing a polyorganosiloxane, wherein the method includes a step of subjecting at least one organic silicon compound having at least one -OX group bonding to a silicon atom in the molecule, wherein X is a hydrogen atom, an alkyl group having 1 to 10 carbon atoms or an alkoxyalkyl group having 2 to 10 carbon atoms, to a condensation reaction in the presence of a catalyst, wherein the catalyst is one obtained by surface treating at least one selected from the group consisting of hydroxides of elements in Group II of the periodic table, hydrates of hydroxides of elements in Group II of the periodic table and oxides of elements in Group II of the periodic table with a silane coupling agent. |
