PROBLEM TO BE SOLVED: To provide an interdental cleaning tool that can prevent wire from falling out of a support piece, even if wire made of polyethylene is used.SOLUTION: An interdental cleaning tool concerning the present invention includes a pair of support pieces disposed at predetermined intervals, a handle part for connecting the pair of support pieces and capable of being held by hands, and wire extending between the pair of support pieces and having one or more multi-filaments. Each multi-filament is formed of polyethylene, and each support piece has a first face of the side opposed to each other and a second face on the other side of the first face. Both ends of the wire penetrate each support piece between the first face and the second face, respectively. The support piece and the handle part are formed of polypropylene having a melt flow rate of 5 g/10 min or more.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT【課題】ポリエチレン製の線材を用いても、線材が支持片から抜けるのを防止できる歯間清掃具を提供する。【解決手段】本発明に係る歯間清掃具は、所定間隔をおいて配置される一対の支持片と、前記一対の支持片を連結し、手で把持可能なハンドル部と、前記一対の支持片の間で延びる、1本または複数のマルチフィラメントを有する線材と、前記各マルチフィラメントは、ポリエチレンにより形成され、前記各支持片は、互いに対向する側の第1面と、当該第1面とは反対側の第2面とを有し、前記線材の両端部は、それぞれ、前記各支持片を前記第1面と第2面との間で貫通し、前記支持片及びハンドル部が、メルトフローレートが5g/10min以上のポリプロピレンにより形成されている。【選択図】図1
