Abstract
A page-wide type liquid ejection head includes a plurality of recording element substrates, each having an ejection port array including a plurality of ejection ports, each ejection port communicating with a pressure chamber including therein a recording element, and a liquid supply path for supplying a liquid to the pressure chamber. The liquid ejection head also includes a flow path member mounting the recording element substrates arranged thereon. The flow path member includes common supply flow paths and individual supply flow paths that connect the liquid supply path to the common supply flow paths, and the individual supply flow paths include portions running obliquely to the direction orthogonal to the longitudinal direction of the liquid ejection head.
