A washing machine including a drum provided with a plurality of recess portions each provided as a polygonal pyramid recessed from one of an inner surface and an outer surface of the drum toward the remaining of the inner surface and the outer surface of the drum, and a plurality of through-holes configured to receive and discharge wash water, the recess portion including a polygonal shape, and a plurality of edges extending from corners of the polygonal side to meet at an apex of the recess portion, and the through-hole is formed through at least one of sides that form the polygonal shape, thereby improving the washing performance due to the recess portion increasing friction with the laundry.
