PROBLEM TO BE SOLVED: To facilitate a manufacturing method of an ejector by reducing the number of part items of the ejector. SOLUTION: A slide mold 63 for a negative pressure taking-out hole for molding the negative pressure taking-out hole, a slide mold 61 for a diffuser for molding the diffuser, and a slide mold 62 for a nozzle for molding the nozzle, are arranged in a mold 60 for molding a body. In this case, the slide mold 61 for the diffuser is penetrated through a through-hole 63a1 arranged in the slide mold 63 for the negative pressure taking-out hole, and the tip of the slide mold 61 for the diffuser is abutted against the tip of the slide mold 62 for the nozzle. The body is molded by injecting a molding material into the mold 60 in its state. COPYRIGHT: (C)2005,JPO&NCIPI
