One aspect of the faucet device of the present invention includes a water spouting port, a valve for switching between discharge and stop of water from the spouting port, and a plasma generator. The spouting port is formed completely or incompletely annularly so that water from the spouting port forms a flow having a hollow portion, and an opening for plasma emission is provided at a position surrounded by the spouting port.本発明の水栓装置の一態様は、吐水口と、吐水口からの水の放出と停止とを切り替えるバルブと、プラズマ生成器とを備える。吐水口からの水が中空部を有する流れを形成するように吐水口は完全又は不完全な環状に形成され、吐水口に囲われた位置にプラズマ放出用の開口が設けられている。
