SOLUTION: This washing implement is formed by clamping staples between at least two drawn polyolefin resin wires substantially orthogonal to the wires, twisting the wires and fixedly holding the washing staple bundles between the wires substantially helically about the wires, wherein the drawn polyolefin resin wire is made of a shape retaining material havig a bending return angleθ, which is obtained by being bent to 180°or 90°, held for one minute, and released for 5 minutes, of 20°or less in either case.
