PROBLEM TO BE SOLVED: To realize a liquid droplet discharge without the feeling of grains, and to efficiently discharge a plurality of independent liquid droplets. SOLUTION: An individual flow passage is made for each discharge energy generation section, and the size, the interval and the area of a plurality of discharging ports are set. Thus, this liquid droplet spraying head is constituted to simultaneously discharge the independent liquid droplets. COPYRIGHT: (C)2008,JPO&INPIT
