Abstract
A nozzle () is made of a sintered metal, and a pressure increasing portion (a mixing portion () and a diffuser ()) is manufactured by plastic-forming a metal pipe. Accordingly, the nozzle () can be manufactured in a short time while high accuracy in machining is maintained. Thus, the cost of manufacturing an ejector () can be reduced.
