PROBLEM TO BE SOLVED: To provide biopsy forceps of excellent durability which can be manufactured at low cost by integrally forming a forceps cup with a drive lever by press work, and in which a boundary part between the forceps cup and the drive lever is resistant to lateral bend to be hard to be deformed. SOLUTION: The drive lever 5a or 5b is formed by residual flat plate material positioned roughly at the same level with an edge part of the forceps cup 3a or 3b formed by recessing the flat plate material roughly by 90 deg. at a rear end part of the forceps cup 3a or 3b. |
