A washing machine according to the present invention is a new washing machine which is compact and can realize uniform and good washing. The plane shape of a washing tub 211 is an approximately rectangular inner shape which is defined by a bottom 213, a pair of long side walls 214a and 214b, and a pair of short side walls 215a and 215b. A pulsator 212 is so provided on the one long side wall 214b out of the pair of long side walls that its center axis 219 is perpendicular to the long side wall 214b. The diameter A of a disk 220 of the pulsator 212 is so set that W<A. Further, a projection 221 of the pulsator 212 is a projection which is long in the radial direction of the disk 220, so that the height thereof from the surface of the disk 220 is large on the side of the circumference of the disk 220.
