Discharge device and air conditioner

摘要

A discharge device (1000) having a less power loss is provided. The discharge device includes a low-potential counter electrode (700) and a discharge electrode (300). The counter electrode is constituted by a plurality of flat-plate portions (731), a first connecting portion (733R), and a second connecting portion (733L) which are integrally formed of one conductive plate body. The plurality of flat-plate portions have elongated shapes and form flat plates disposed almost parallel to each other. The first connecting portion connects one-end portions of the elongated shapes of the flat-plate portions. The second connecting portion connects the other-end portions of the flat-plate portions. The discharge electrode (300) forms a wire, is arranged to extend among the flat-plate portions in a lengthwise direction, and has a higher potential than the counter electrode.
