PROBLEM TO BE SOLVED: To provide a brush disposal to be burnt by fitting a plurality of bristles made of synthetic fiber between a plurality of core pieces along a longitudinal direction, integrately stranding the pieces, and radially extending the bristles around the core pieces. SOLUTION: A core material 1 consists of on piece of synthetic resin mono- filament is bent back to be two pieces at a tip of a brush, and a plurality of bristles 2 made of synthetic fiber are fitted crosswise into these core pieces 1. The two core pieces 1 are stranded with the bristles 2 interposed therebetween, then the bristles 2 are spirally wound in the form of spiral stairs along the longitudinal direction of the core pieces 1 while it is extended radially around the core pieces 1. Accordingly, the bristles 2 can be held and fixed surely as in the case of wires, and this brush can be disposed and burnt without requiring sorting work for every material when it is made unnecessary.
