A tube-end device for fire extinguishment jets and sprays pressurized and fed water, seawater, or aqueous fire-extinguishing agent from a tube end. The tube-end device for fire extinguishment is provided with: an induction electrode unit disposed in an emission space side of a nozzle unit positioned inside the tube end; a water-side electrode unit disposed at a position of the interior of a tube main body in contact with fire-extinguishing water; a voltage applying device which applies an external electric field, which is generated by applying a voltage between the induction electrode unit and the water-side electrode unit, to the water, seawater, or fire-extinguishing agent in the process of jetting from the nozzle unit, electrically charges jetted particles, and emit the particles; and a battery which supplies power to the voltage applying device.
