PROBLEM TO BE SOLVED: To provide an interdental cleaner capable of enhancing raking property on stain in interdental spaces while reducing at least one of insertion resistance into interdental spaces and extracting resistance from interdental spaces.SOLUTION: An interdental cleaner comprises: a base part comprising a shaft part (20)； and a cleaning part (40). The cleaning part (40) has a cleaning part body (50) and a plurality of brushes (60). The plurality of brushes (60) each have at least one of an inclined brush facing the tip, having a shape which is gradually inclined to the tip side of the shaft part (20) as being separated from the outer peripheral surface of the cleaning part body (50), and an inclined brush facing the base end, having a shape which is gradually inclined to the base end side of the shaft part (20) as being separated from the outer peripheral surface of the cleaning part body (50).SELECTED DRAWING: Figure 2COPYRIGHT: (C)2020,JPO&INPIT【課題】歯間への挿入抵抗及び歯間からの抜き取り抵抗の少なくとも一方を低減しつつ、歯間の汚れの掻き取り性を高めることが可能な歯間清掃具を提供すること。【解決手段】軸部（２０）を含む基部と清掃部（４０）とを備え、清掃部（４０）は、清掃部本体（５０）と複数のブラシ（６０）とを有し、複数のブラシ（６０）は、清掃部本体（５０）の外周面から離間するにしたがって次第に軸部（２０）の先端側に向かうように傾斜する形状を有する先端向き傾斜ブラシ、及び、清掃部本体（５０）の外周面から離間するにしたがって次第に軸部（２０）の基端側に向かうように傾斜する形状を有する基端向き傾斜ブラシの少なくとも一方を有すること。【選択図】図２
