A liquid ejection head is provided that is adapted, when the ejection of comparatively small ink droplets by one print head is required, to not only increase a printing speed and a printing resolution but also to prevent the occurrence of cavitation. The liquid ejection head includes: nozzles, for which heaters are formed to generate thermal energy used to eject ink; and bubble generation chambers, for which ejection ports are formed for ejecting ink upon the application of thermal energy provided by the heaters. Further, a partition wall is formed in each bubble generation chamber at a position opposite the ejection port.
