A liquid ejection recording head includes a recording element substrate including a plurality of energy generating elements for generating energy for ejecting liquid, and a flow passage-forming member, connected to the recording element substrate, comprising a plurality of ejection outlets corresponding to the plurality of energy generating elements and plurality of flow passages communicating with the ejection outlets. The flow passage-forming member includes a hole array having holes arranged so as to surround the flow passages and a communication passage, for establishing communication between adjacent holes, at a position close to the recording element substrate.
