An ozone generating injection apparatus and a backpack type ozone disinfecting apparatus which spray a high concentration ozone gas, further reduce the weight and size, and enable good operability with low cost are provided. The ozone generating injector includes a discharge tube for generating ozone by applying a high voltage between the electrodes while introducing a gas containing oxygen or oxygen from one end side and a discharge tube directly connected to the other end side of the discharge tube and generated in the discharge tube A connection member having one or more passageways through which ozone passes and a nozzle portion including one or more capillaries projecting in the ozone flow direction in communication with the passage of the connection member. Provided are an ozone generating injection apparatus and a backpack type ozone disinfecting apparatus capable of spraying a high concentration ozone gas by providing a nozzle part directly connected to a discharge tube, further making it lightweight and compact at low cost and good operability.高濃度のオゾンガスを噴霧し、さらに軽量、小型にして低価格で良好な操作性を可能とするオゾン発生噴射装置並びに背負い形オゾン消毒装置を提供する。 オゾン発生噴射装置は、酸素又は酸素を含む気体を一端側から導入させつつ電極間に高電圧を印加してオゾンを発生させる放電管と、放電管の他端側に直結され放電管で発生したオゾンが通過する1個又は複数の通過路を有する接続部材と、接続部材の通過路に連通してオゾンの流れ方向に突設する1個又は複数の細管を含むノズル部と、を含む。放電管に直結するノズル部を設けることで高濃度のオゾンガスを噴霧し、さらに軽量、小型にして低価格で良好な操作性を可能とするオゾン発生噴射装置並びに背負い形オゾン消毒装置を提供する。
