A treatment tool for an endoscope includes a forcep sheath, a first forcep cup and a second forcep cup which are attached to a distal end of the forcep sheath, and which cooperate with each other to be openable/closable as a whole, an operation wire which is movably arranged in the forcep sheath along an axial direction thereof, which is connected to the first forcep cup and the second forcep cup, and which opens/closes the first forcep cup and the second forcep cup when moved in its axial direction, wherein a sharp needle-shaped portion is formed on a distal end of the first forcep cup, the sharp needle-shaped portion extending farther than a distal end of the second forcep cup, and the sharp needle-shaped portion is arranged so that at least a portion thereof overlaps the second forcep cup.
