PROBLEM TO BE SOLVED: To provide a washing brush which has high washing performance and can be quickly manufactured at a low cost by enhancing stiffness of bristles of a brush piece. SOLUTION: This washing brush is used to wash out dirt etc. stuck on a surface to be washed. The washing brush is formed of a seat, a channel brush, and a stopper metal. The channel brush is formed of a core wire, brush pieces, and band shape bodies. A flat synthetic resin foamed body is used for the brush piece. A plurality of slits are formed asymmetrically with respect to the center part of the brush piece. The channel brush is formed by clamping the center part of the brush piece between the core wire and the band shape body, thereafter the channel brush is wound around the seat and fixed by the stopper metal.
