PROBLEM TO BE SOLVED: To provide an interdental cleaning tool capable of achieving both ease of insertion into an interdental space and scraping property of dental plaque and sufficient massage power to the gingiva. SOLUTION: An interdental cleaning tool 1 has a base material portion 10 having a base portion 11 and a shaft portion 12 extending from the base portion 11, and a shaft portion extending at least 16 mm from the tip end of the shaft portion 12 toward the base end. A covering portion 21 for covering the 12 and a soft portion 20 having a plurality of protrusions 22 protruding from the coating portion 21 are provided, and the covering portion in the range of 15 mm to 20 mm from the tip end to the base end of the shaft portion 12 is provided. In the region of 21, the ratio of the total area (A2: mm2) of the bottom surface of the protrusion 22 serving as the boundary with the covering portion 21 to the surface area (A1: mm2) of the covering portion 21 is set to 20% to 70%. ..
