PROBLEM TO BE SOLVED: To provide a self-defense instrument easy to operate and having excellent portability. SOLUTION: The self-defense instrument has: a cylindrical container 1 closed at one end; a bag-like member 6 disposed in the container 1 and filled with liquid 7 against ruffians; ejection means 9-11 provided at one end of the cylindrical container 1 and having powder or the like; and a rupture means 3 provided at the other end of the cylindrical container 1, pointing its sharp tip part inward to rupture the bag-like member 6. Sufficient ejection pressure is generated even with a small amount of powder, but the container filled with the liquid against a ruffian requires strength enough to withstand an explosion, and in view of the case where the liquid against ruffians cannot be applied to the ruffian as it is, the rupture means for rupturing the bag-like member when passing through is newly provided to positively jet the internal liquid even if adopting a member with sufficient strength as the container filled with the liquid against a ruffian. As a result, stability in storage and at the explosion of powder is improved with the bag-like member with high strength, and the liquid against the ruffian is positively applied to the ruffian.
