An air-blowing apparatus having discharge device comprising: an air supply passage having an air outlet from which air is blown off; a discharge device provided for generating active ingredients and disposed outside the air supply passage; and an introducing pipe having one end connected to the discharge device and another end disposed in the air supply passage, and the introducing pipe being provided for introducing the active ingredients into the air supply passage, wherein the other end of the introducing pipe includes an opening that is characterized by a plane, the introducing pipe is arranged such that, in a state where the other end side of the introducing pipe is disposed in the air supply passage, the opening plane and a main stream direction of an air flow which flows through the air supply passage at a predetermined point of the opening are substantially parallel to each other, the introducing pipe has a protruding portion on the other end side, the protruding portion linearly protruding toward an inside of the air supply passage from a wall portion which defines the air supply passage, and the discharge device is either an electrostatic atomization device for generating charged water particles as the active ingredients or an ion generator for generating air ions as the active ingredients, characterized in that the protruding portion is inclined with respect to a tangential plane of an inner surface of the wall portion at an intersection between a center axis of the protruding portion and the inner surface of the wall portion such that the other end is disposed on a downstream side of the air supply passage. an air supply passage having an air outlet from which air is blown off; a discharge device provided for generating active ingredients and disposed outside the air supply passage; and an introducing pipe having one end connected to the discharge device and another end disposed in the air supply passage, and the introducing pipe being provided for introducing the active ingredients into the air supply passage, wherein the other end of the introducing pipe includes an opening that is characterized by a plane, the introducing pipe is arranged such that, in a state where the other end side of the introducing pipe is disposed in the air supply passage, the opening plane and a main stream direction of an air flow which flows through the air supply passage at a predetermined point of the opening are substantially parallel to each other, the introducing pipe has a protruding portion on the other end side, the protruding portion linearly protruding toward an inside of the air supply passage from a wall portion which defines the air supply passage, and the discharge device is either an electrostatic atomization device for generating charged water particles as the active ingredients or an ion generator for generating air ions as the active ingredients, characterized in that the protruding portion is inclined with respect to a tangential plane of an inner surface of the wall portion at an intersection between a center axis of the protruding portion and the inner surface of the wall portion such that the other end is disposed on a downstream side of the air supply passage.
