Ionizer unit

The present invention provides an ionizer unit which is easy to set and is not easy to generate a radiation noise problem. The ionizer unit comprise a rectangular electrode substrate (11), a linear discharge electrode 12 configured on the surface of the electrode substrate 11 and formed into a continuous linear shape along the length direction Y of the electrode substrate (11); a boost transformer(14) electrically connected with the linear discharge electrode 12 and specially arranged relative to the linear discharge electrode 12; and a box body 17 integrally storing the electrode substrate 11 and the boost transformer 14. 本发明提供种易于设置且不易产生辐射噪声的问题的电离器单元。该电离器单元具备：长方形的电极基板（11）；线状放电极（12），其配置于电极基板（11）的表面，形成为沿着电极基板（11）的长度方向Y连续的1根线状；升压用的升压变压器（14），其电连接于1根线状放电极（12），相对于该1根线状放电极（12）专用地设置；以及箱体（17），其体地收纳电极基板（11）以及升压变压器（14）。
