Also, the electric circuit of the conductive sheet S and the charging means 3 (the GND contact on the ground side of the power supply circuit)
22 and a high voltage generation circuit (not shown)), an electric field is less likely to be generated between the housing 6 and the wall surface W. It is surely prevented. Furthermore, since the conductive sheet S is formed of a nonwoven fabric, it is difficult to tear and is easy to handle, and since the nonwoven fabric contains copper, the conductivity of the conductive sheet S is high. The effect of preventing contamination is improved.

At least the back surface portion is formed of an antistatic material. In this case, the entire housing 6 is formed of PS (polystyrene) which contains a new water-based polymer having a current-carrying action and serves as an antistatic material. Therefore, in this case, since the rear surface of the housing 6 is formed of the antistatic material,
The portion of the housing 6 that is in close proximity to the wall surface W is less likely to be charged, and the wall surface W is reliably prevented from being stained.

Further, in the air purifier installation structure of this embodiment, the portion formed of the antistatic material of the housing 6 and the electric circuit of the charging means 3 are electrically connected.

If the rear surface of the housing 6 is in contact with the conductive sheet S, the conductive sheet S and the charging means 3
Is electrically connected to the electric circuit through the rear surface portion, and the wiring cord C in the above embodiment is not required. Therefore, in this case, the rear portion of the housing 6 is less likely to be charged, and furthermore, an electric field is less likely to be generated between the rear portion and the wall surface W, and the wall surface W is more reliably prevented from being stained. Will be. The rest is configured in the same way as the embodiment shown in FIGS.
