PROBLEM TO BE SOLVED: To provide an interdental tooth brush which can used while being bent and is excellent in durability. SOLUTION: In the interdental tooth brush 1, a strand wire brush 3 is formed in a state where it is buried into a handle body 2. The brush 3 consists of: a buried part 3a buried in the handle body 2; and a brush part 3b transplanted projecting from the handle body 2. The handle body 2 has a fixed part 2a integrated with the buried part 3a of the brush 3 formed on the side of an end part where the brush 3 is buried, and has a flexibly deformable part 2b which is formed at a part adjacent to the fixed part and can flexibly be deformed by operation with the thumb and the index finger in a state where the fixed part 2a is held between the thumb and the index finger.
