PROBLEM TO BE SOLVED: To provide an interdental cleaner capable of improving functions as the interdental cleaner such as a plaque removal performance and massage effects.SOLUTION: The interdental cleaner constitutes a cleaning part 2 for interdental cleaning, of a core base material part 12 and a cleaning soft part 21. The cleaning soft part 21 includes a cover part 21a for covering the core base material part 12, and a plurality of cleaning protrusions 21b and 21c protruding outward from the cover part 21a. Out of adjacent cleaning protrusions, the length of first cleaning protrusions 21b disposed along a datum plane BS substantially orthogonal to a finger grip direction of a handle part is differentiated from the length of second cleaning protrusions 21c other than those.SELECTED DRAWING: Figure 6COPYRIGHT: (C)2017,JPO&INPIT【課題】プラークの除去性能やマッサージ効果などの歯間清掃具としての機能を向上可能な歯間清掃具を提供する。【解決手段】芯基材部12と清掃用軟質部21とで歯間清掃用の清掃部2を構成した歯間清掃具であって、清掃用軟質部21は、芯基材部12に被覆される被覆部21aと、被覆部21aから外方へ突出する複数の清掃用突起部21b、21cとを有し、隣接する清掃用突起部のうちの、ハンドル部の指による摘み方向と略直交する基準面BSに沿って配置される第1清掃用突起部21bと、それ以外の第2清掃用突起部21cとで長さを相違させた。【選択図】図6
