PROBLEM TO BE SOLVED: To prevent density variations from occurring by an inexpensive structure in the discharge of a liquid containing fine particles. SOLUTION: The liquid droplet discharge head comprises nozzles which discharge a liquid containing fine particles as liquid droplets, a pressure chamber communicating with the nozzles, a piezoelectric element which varies the cubic capacity of the pressurization chamber, and a supply channel which makes a common liquid chamber which stores the liquid to be supplied to the pressure chamber communicate with the pressure chamber. A plurality of the common liquid chamber side supply openings of the supply channel are arranged in different positions in a gravity direction. COPYRIGHT: (C)2007,JPO&INPIT
