PURPOSE: A washing machine is provided to facilitate production of a pulsator forming water current for washing, reduce the manufacturing cost, and improve durability. CONSTITUTION: A washing machine has a pulsator(30) stirring washing water and laundry. The pulsator is combined to a washing shaft(22). The pulsator comprises a rotating plate(31) with the center combined to the washing shaft; upper blades(32) protruded on the rotating plate and arranged radially; and lower blades(33) protruded on the bottom surface of the rotating plate and arranged radially. The rotating plate and upper and lower blades are made of the same stainless steel. Each part of the pulsator is integrally formed. The manufacturing cost of the pulsator is simplified by the simplified structure. The thermal deformation degree of each part of the pulsator is regular and thus the durability of the pulsator is improved.
