PROBLEM TO BE SOLVED: To provide a brush which does not generate bubbles at the time of coating. SOLUTION: The writing brush comprises a brush body 1 of a cylindrical shape to pass liquid in a hollow part 1a and a coating part 2 which is constituted to a brush form by bundling plural pieces of extremely fine hollow pipes 2a which flexibly bend and have hollow parts communicating with the hollow part 1a at the one end of the writing brush body 1. Then, the liquid does not exist among the hollow pipes 2a in coating of the liquid and therefore, air does not intrude into the liquid and the generation of the bubbles is averted even when the liquid is applied on a material having ruggedness. |
