  The first contact portion P1 and the second contact portion P2 constitute a holding portion in which the conductive member 20 holds and holds the coated conductive wire 10.

  The support member 30 supports the conductive member 20. The support member 30 prevents the conductive member 20 from separating from the coated conductive wire 10.

  The support member 30 includes a first support member 31 and a second support member 32. The first support member 31 has a first portion 311, a second portion 312, and a connection portion 313.

  The first portion 311 has a plate-like shape. The first portion 311 abuts on the outer surface of the first plate-like portion 21 (the main surface on the side opposite to the side in contact with the coated wire 10). The second portion 312 has a plate-like shape. The second portion 312 is spaced apart from the first portion 311 in a predetermined direction.

  The high voltage circuit 50 generates a high voltage from a voltage supplied from a power supply (not shown). One side of the high voltage circuit 50 is electrically connected to the conductive line 11 by the line 41. The other side of the high voltage circuit 50 is electrically connected to the conductive member 20 (the first plate-like portion 21 and the second plate-like portion 22) by a wire 42. The first plate-like portion 21 and the second plate-like portion 22 are connected in parallel.

  The high voltage circuit 50 applies a high frequency and a high voltage between the conductive member 20 and the conductive wire 11. Thereby, a potential difference is generated between the conductive member 20 and the conductive wire 11. The voltage applied between the conductive member 20 and the conductive wire 11 is preferably an alternating voltage.

  By applying an alternating voltage to reverse the polarity of the voltage applied between the conductive wire 11 and the first plate-like portion 21 and between the conductive wire 11 and the second plate-like portion 22, Body barrier discharge can be repeated.

  Since plasma is generated substantially uniformly along the first contact portion P1 and the second contact portion P2 to one end side and the other end side in the extending direction of the coated conductive wire 10, plasma can be generated over a wide range it can. Thereby, the plasma can be efficiently brought into contact with the processing target gas.

  By passing a gas to be treated such as air through the plasma generation apparatus 1 while generating plasma, impurities contained in the gas to be treated such as inactivation of bacteria and viruses present in the gas to be treated or odor Gas can be decomposed and removed. Thereby, the gas to be treated can be purified.

It is good also as a direction (AR1 direction) to do. By blowing the gas to be treated in the blowing direction, the gas to be treated directly contacts the first contact portion P1 and the second contact portion P2, and plasma can be contained in the gas to be treated.

  The blowing direction of the gas to be treated may be a direction in which the first plate-like portion 21, the coated wire 10, and the second plate-like portion 22 are aligned, or may be an extending direction of the coated wire 10 . When the blowing direction is the direction in which the first plate portion 21, the coated wire 10, and the second plate portion 22 are aligned, a part of the gas to be treated is circumferentially along the circumferential surface of the coated wire 10. By flowing, the gas to be treated can contain plasma. In the case where the blowing direction is the extending direction of the coated lead 10, a part of the gas to be treated flows along the extending direction of the coated lead 10 on the circumferential surface of the coated lead 10, thereby generating plasma in the gas to be treated. Can be included.

  By grounding the conductive member 20, safety can be secured even when the user touches the conductive member 20 exposed to the outside.
