It is an object of the present invention to provide a polyalkyleneimine alkyleneoxide copolymer, which is suitably used as a builders for a detergent, a detergent, a water treatment agent, a dispersant and the like and which can exert high basic performance in point of the detergency or the like, a production method thereof, and use thereof. The present invention is directed to a polyalkyleneimine alkyleneoxide copolymer comprising an alkyleneimine monomer unit having polyalkyleneoxide, wherein the polyalkyleneoxide has an end structure containing at least one selected from the group consisting of: (1) -CO-R<SUP>2</SUP>-COOX; (2) -CH<SUB>2</SUB>CH(OH)-R<SUP>3</SUP>; (3) -CH<SUB>2</SUB>CH(OH)CH<SUB>2</SUB>-O-R<SUP>4</SUP>; and (4) -C(O)-NH-R<SUP>5</SUP>, wherein R<SUP>2 </SUP>represents an alkylene group having 2 to 8 carbon atoms, an alkenylene group having 2 to 8 carbon atoms, an arylene group having 6 to 14 carbon atoms or a sulfoalkylene group having 2 to 8 carbon atoms; R<SUP>3 </SUP>represents an alkenyl group having 2 to 6 carbon atoms, an aryl group having 6 to 14 carbon atoms, a sulfoalkyl group having 2 to 6 carbon atoms or a hydroxyalkyl group having 2 to 6 carbon atoms; R<SUP>4 </SUP>represents a hydrogen atom, an alkyl group having 2 to 8 carbon atoms, an alkenyl group having 2 to 6 carbon atoms, an aryl group having 6 to 14 carbon atoms or a sulfoalkyl group having 2 to 6 carbon atoms; R<SUP>5 </SUP>represents an alkyl group having 2 to 8 carbon atoms, an alkenyl group having 2 to 8 carbon atoms, an aryl group having 6 to 14 carbon atoms or a sulfoalkyl group having 2 to 6 carbon atoms; and X represents a hydrogen atom, an alkaline metal atom, an alkaline earth metal atom, an ammonium group or an organic ammonium group.
