Title:
液体吐出ヘッド
Document Type and Number:
Japanese Patent JP7419008
Kind Code:
B2
Abstract:
A liquid ejection head includes an ejection orifice forming member having a liquid ejection orifice and a substrate having a liquid flow path such that a liquid circulation flow path is formed between the ejection orifice forming member and the substrate. The liquid circulation flow path includes a bubble generation chamber facing the liquid ejection orifice and is branched from the liquid flow path so as to pass through the bubble generation chamber and join the liquid flow path. The substrate has an ejection energy generation element arranged to face the bubble generation chamber and a circulation energy generation element arranged at a different position to face the liquid circulation flow path. The gap between the ejection energy generation element and the ejection orifice forming member is different from the gap between the circulation energy generation element and the ejection orifice forming member.
