Abstract: An interdental cleaning tool that achieves both easy insertion between teeth and improved cleaning effect is provided. The interdental cleaning tool 1 includes a base material portion 10 including a base section 11 and a shaft section 12 extending from the base section 11, and a soft portion 20 covering at least a part of the shaft section 12. The at least the part of the shaft section 12 has a first outer dimension X1 defined in a first direction D1 and a second outer dimension X2, defined in a second direction D3 perpendicular to the first direction D1 and smaller than the first outer dimension X1, in a cross section of the shaft section 12 perpendicular to an axial direction of the shaft section 12.
