Abstract: The present invention provides a quartz glass single hole nozzle for feeding fluid capable of performing high-precision control of a flow rate, a burner for heat processing equipped with the quartz glass single hole nozzle, a quartz glass multihole burner head for feeding fluid preferably used in flame processing or the like, and a quartz glass burner for heat processing equipped with the multihole burner. By using the nozzle, even if a distal end portion of the quartz glass burner, namely the nozzle is broken by contact with a workpiece or the like, it is enough to only replace the broken nozzle with a new one without a necessity for replacing the entire expensive quartz glass burner. When applying the nozzle to a metal burner, there can be given usefulness of the quartz glass such as heat resistance and contamination resistance or the like.
