PROBLEM TO BE SOLVED: To provide a new design for an atomization head capable of surely cooling a fuel distributed by a secondary circuit by permanent circulation of fuel distributed by a primary circuit, and eliminating probability of coking. SOLUTION: A part of a fuel injector corresponding to the secondary circuit is cooled through fuel circulation with permanent flow rate of the primary circuit. The secondary circuit 19 is connected to a distribution chamber 30 perforated by a plurality of fuel injection orifices, and the primary circuit 17 comprises at least one passage section 86 adjacent to the distribution chamber, for its cooling.
