PROBLEM TO BE SOLVED: To provide a deflector useful for jetting with a further wider angle in the thickness direction while maintaining an even jetting density, and a jetting nozzle using the same. SOLUTION: The jetting nozzle is provided with: a main flow path 2 formed extending in the axis direction on a nozzle body 1; a discharge flow path 3 having a flow path diameter reduced at the down stream side of the main flow path, and having a discharge opening (jetting hole) 4 opening at the tip end part of the nozzle body 1; and a deflector 7 disposed in the main flow path 2 of the upstream side of the discharge opening 4 for dividing fluid from the upstream, wherein a concave portion or a groove portion 8 is formed on the downstream plane of the deflector, and a collision wall 9 on which the fluid divided by the deflector 7 can collide is formed on the inside wall of the nozzle body 1 between the upstream end of the deflector 7 and the discharge flow path 3.
