PROBLEM TO BE SOLVED: To provide a twist brush which can easily be manufactured in many kinds by bending a metal wire to form metal wire parts so as to be in parallel and changing the number of pieces of the parallel metal wire parts according to the kind of a product. SOLUTION: A formed metal wire 2, in which three or more metal wire parts 1a are in parallel, is formed by bending the metal wire 1, and a plurality of pieces of brush materials 3a are arranged among the metal wire parts 1a of the formed metal wire 2 to be orthogonal to each other and twisted, so that the brush materials 3a are helically arrayed on the formed metal wire 2.
