Provided are an ozone-generating spray device and a backpack-type ozone sterilization device, which are lightweight and inexpensive, have a small size and exhibit excellent usability, and with which highly concentrated ozone gas can be sprayed. This ozone-generating spray device includes: an electrical discharge tube in which, while oxygen or an oxygen-containing gas is introduced from one end side thereof, a high voltage is applied between electrodes to generate ozone a connection member which is directly coupled to another end side of the electrical discharge tube, and which is provided with at least one passage through which the ozone generated in the electrical discharge tube passes and a nozzle which communicates with the at least one passage of the connection member, and which includes at least one fine tube provided protruding in a flow direction of the ozone. As a result of providing the nozzle directly coupled with the electrical discharge tube, an ozone-generating spray device and a backpack-type ozone sterilization device can be provided, which are lightweight and inexpensive, which have a small size and exhibit excellent usability, and with which highly concentrated ozone gas can be sprayed.本發明提供一種可噴出高濃度臭氧氣體的霧氣,又可設成輕量、小型且低價並有良好操作性之臭氧產生噴射裝置及背負式臭氧消毒裝置;臭氧產生噴射裝置包含:放電管,一邊使氧或含氧的氣體從一端側導入,一邊在電極間施加高電壓以產生臭氧;連接構件,具有與放電管另一端側直接連結,以供藉放電管產生的臭氧通過之1個或複數個通過路徑;及噴嘴部,包含與連接構件的通過路徑連通且突出設置於臭氧的流動方向的1根或複數根細管。又提供一種藉設置與放電管直接連結的噴嘴部,可噴出高濃度臭氧氣體的霧氣,又可設成輕量、小型且低價並具有良好操作性之臭氧產生噴射裝置及背負式臭氧消毒裝置。1‧‧‧臭氧產生噴射裝置2‧‧‧放電管3‧‧‧連接構件4‧‧‧噴嘴部5‧‧‧管本體5a‧‧‧管本體的一端部5b‧‧‧管本體的另一端部6‧‧‧空隙7‧‧‧高電壓電極8‧‧‧接頭構件10‧‧‧接地電極12‧‧‧通路14‧‧‧連結埠20‧‧‧空間22‧‧‧連結部24‧‧‧通過路徑24a‧‧‧通過路徑出口26‧‧‧嵌合孔28‧‧‧保持部30‧‧‧O型環32‧‧‧細管32a‧‧‧前端出口34‧‧‧支撐罩34a‧‧‧開口50‧‧‧冷卻套部52‧‧‧霧氣噴嘴部54‧‧‧框體56‧‧‧凹部58‧‧‧冷卻用管路66‧‧‧噴嘴保持部68‧‧‧霧氣噴嘴68a‧‧‧微細孔70‧‧‧分岐配管69‧‧‧噴嘴元件F‧‧‧臭氧的流動方向S‧‧‧水霧氣
