PROBLEM TO BE SOLVED: To enlarge a spraying range with a simple structure and a small size. SOLUTION: The multi-injection nozzle has a short cylinder shape having an internal space. In this nozzle, a central injection port having a cone spraying pattern is formed on a tip end center at an injection side and a cone surface having a diameter shrinking toward a tip end side is formed on an outer periphery surface near the tip end. A plurality of outer periphery injection ports having a sector spraying pattern communicating with the internal space are arranged on the cone surface at a circumferential interval. These outer periphery injection port is constituted such that a longitudinal direction of the sector spraying pattern becomes the same direction as an axis direction of the nozzle or an inclined direction at a predetermined angle. A full cone spraying pattern of an approximately large circle is formed by combining spraying patterns of a fluid sprayed from the internal space through the central injection port and the outer periphery injection port.
