ABSTRACT:
The present invention is directed to a gas supply nozzle plate constructed by laminating a plurality of metal members each having a fluid path and branch. A fluid nozzle plate member provided by the invention has high sealing at a joined part, and high reliability even when used in high vacuum or at a high temperature. The fluid nozzle plate member comprises a plurality of plate-like metal members each having a fluid path and/or a branch. In this case, the plurality of plate-like metal members are laminated, and the laminated surfaces thereof are joined together by press forging.
