To provide a sterilizer capable of sufficiently destroying or inactivating microbes even in the case that a gas containing the microbes passes between a discharge electrode and a counter electrode at an extremely high speed.
The sterilizer is provided with the discharge electrode 2 and the counter electrode 3 and can scatter electrons or the like by discharge at a high speed between the discharge electrode 2 and the counter electrode 3 and destroy or inactivate the microbes in air passing through the discharge area 8. In order to widen the discharge area 8 and improve sterilization efficiency, the discharge electrode 2 has a coil shape in which turns are adjacently arranged in a direction orthogonal to the air flow direction of an air flow passing area 5 and the circular maximum diameter parts of the respective turns are parallelly positioned in the direction along the air flow direction. The counter electrode 3 has a plate shape with a flat surface parallel with a width along the air flow direction of the air flow passing area 5.
