The applicator is inserted inside a living body and applies a mixed solution on a region inside the living body. The applicator comprises: a nozzle, which is provided with a long main nozzle body into which gas and multiple kinds of liquids are supplied, and a nozzle head, which is provided on the leading end side of the main nozzle body and which sprays a mixed liquid of the gas and the multiple kinds of liquids supplied to the main nozzle body; and a sheath into which the main nozzle body is inserted so as to be movable relative to same in the longitudinal axial direction thereof. A gap is provided between the main nozzle body and the sheath. The gap functions as a discharge pathway for gas inside the living body to be discharged from the living body when pressure inside the living body increases. Multiple side holes, each of which communicates with the gap, are formed on the circumference of the sheath at multiple equally spaced positions along the longitudinal direction thereof. |
