PROBLEM TO BE SOLVED: To provide a discharge unit capable of directly connecting a discharge electrode and a voltage supply unit without using a harness, and optimally keeping the inter-electrode distance between the discharge electrode and a counter electrode.SOLUTION: A discharge electrode (70) is formed into a plate-like shape, and includes a slender support part (71), a plurality of discharge needles (72) protruding outward in a width direction of the support part (71) from the support part (71), a connection part (82) connected to a voltage supply part (30), and contact parts (80) consecutively formed between the support part (71) and the connection part (82). The contact part (80) is formed with a fragile part (86) having lower rigidity than the support part (71).COPYRIGHT: (C)2016,JPO&INPIT【課題】ハーネスを用いることなく放電電極と電圧供給部とを直に接続でき、且つ放電電極と対向電極との間の電極間距離を最適に保つことができる放電ユニットを提供する。【解決手段】放電電極(70)は、板状に形成され、細長の支持部(71)と、支持部(71)から支持部(71)の幅方向へ突出する複数の放電針(72)と、電圧供給部(30)に接続される接続部(82)と、支持部(71)と上記接続部(82)との間に連続して形成される連絡部(80)とを有し、連絡部(80)には、支持部(71)よりも剛性の低い脆弱部(86)が形成されている。【選択図】図12
