PROBLEM TO BE SOLVED: To provide an ejector capable of ensuring airtightness without executing a sink test.SOLUTION: An ejector 11 generating a negative pressure by jetting a pressurized fluid from a nozzle 91 toward a diffuser passage 41 and sucking a fluid in a suction passage 51, includes the nozzle 91, the diffuser passage 41 for leading the pressurized fluid jetted from the nozzle 91 therein, and a main body block 21 joining the diffuser passage 41 at a downstream-side position with respect to the nozzle 91 and having the suction passage 51 inside thereof. On an outer side face of the main body block 21, three ports of a cylindrical supply port 61 communicated with the nozzle 91 and supplying the pressurized fluid to the nozzle 91, a cylindrical exhaust port 71 communicated with the diffuser passage 41 and discharging the pressurized fluid jetted from the nozzle 91 to the diffuser passage 41, and a cylindrical suction port 81 communicated with the suction passage 51 are integrally formed. |
