A disposable surgical scalpel includes a sharp blade for cutting skin or body parts in a surgical operation, a blade-fixing member to which a rear end of the sharp blade is integrally fixed such that the sharp blade can reciprocate together with the blade-fixing member, and a handle disposed enclosing the blade-fixing member such that the sharp blade fixed on the blade-fixing member can be completely projected out of and inserted into the handle.
