PROBLEM TO BE SOLVED: To provide a discharger of which maintenance such as removal of dusts adhered to a discharge needle is simplified. SOLUTION: The discharger 100 has an inside air flow path 104 linearly extending in a horizontal direction, and a sleeve-shaped discharge needle unit 112 arranged at an air supply side, and an opposing electrode unit 114 arranged at an ionized air discharging side are disposed in the inside air flow path 104. When carrying out the maintenance, the discharge needle unit 112 can be pulled out from a discharger main body 102 by making the discharge needle unit 112 move toward an upstream side (backward) of the inside air flow path 104 in an axial direction, after turning the discharge needle unit 112 around the axial line and releasing its screw connection with the discharger main body.
