PROBLEM TO BE SOLVED: To provide a disposable interdental brush carried extremely compactly and sanitarily by simplifying it by configuring a part of the interdental brush by a packaging material and substantially reducing the price of a final product by reducing useless materials and man-hours. SOLUTION: The interdental brush includes: a brush body 10 provided with a flocked portion 11 on one end side of a flexibly deformable shaft portion 12; and a sheet-like packaging material 20 for covering the brush body 10 and can be thermally bonded. The sheet-like packaging material 20 includes: a hollow first thermally bonded portion 21 for housing the flocked portion 11 of the brush body 10; a second thermally bonded portion 22 for holding the other end side of the shaft portion 12 of the brush body; and separation means 23 for removing a first thermally bonded portion 21 from the second thermally bonded portion 22. After removing the first thermally bonded portion 21 of the sheet-like packaging material 20, the remaining second thermally bonded portion 22 forms the holding portion of the brush body 10.
