PROBLEM TO BE SOLVED: To provide a liquid discharge head which eliminates a variation in the discharge amount by a crosstalk, by suppressing the occurrence of the deformation of a side wall of an individual liquid chamber. SOLUTION: The liquid ejection head comprises a liquid droplet ejection port 2, and the individual liquid chamber 3 which communicates with the ejection port 2. A plurality of side surfaces of the side wall composing the liquid chamber 3, are formed in such a shape as to protrude toward the inside of the liquid chamber 3. COPYRIGHT: (C)2007,JPO&INPIT
