PROBLEM TO BE SOLVED: To enhance the performance of mixing air with a fuel to make effective use of air by widely spreading an air vortex from the central space portion of a vortex chamber to both side space portions thereof. SOLUTION: An outside peripheral edge portion 10 positions at the outside from the axis 4 of an injection hole 3 in view of the center 5 of a vortex chamber 2 among the end peripheral edge part 9 of the hole, in the portion at which the hole 3 communicates with the vortex chamber 2. A smooth connection face 13 for smoothly connecting the peripheral face portion 11 in the direction of outside of the hole 3 with the peripheral face 12 of the vortex chamber 2 is formed. In an inside peripheral edge portion 14 positioning at the side opposite to the outside peripheral edge portion 10 among the end peripheral edge part 9, the peripheral face portion 15 in the direction of inside of the hole 3 and the peripheral face 12 of the vortex chamber 2 are connected in such a state as to make an acute angle with each other.
