PROBLEM TO BE SOLVED: To provide a liquid discharge head which inhibits strength from being affected by stress even if the stress remains in a recording element substrate and a support member, and to provide a liquid discharge device.SOLUTION: Supply passages are formed in recording element substrates 110, 111. Support members 2a, 2b are respectively joined to the recording element substrates 110, 111 and support the recording element substrates 110, 111. Ink communication passages capable of supplying an ink to the supply passages are formed in the support members 2a, 2b. Width direction lengths of the recording element substrates 110, 111 are longer than width direction lengths of the support members 2a, 2b. 【課題】記録素子基板及び支持部材に応力が残留したとしても、これによって強度が影響を受けることを抑えることができる液体吐出ヘッド及び液体吐出装置を提供する。【解決手段】記録素子基板１１０、１１１には、供給路が形成されている。支持部材２ａ、２ｂは、記録素子基板１１０、１１１と接合されて記録素子基板１１０、１１１を支持する。支持部材２ａ、２ｂには、供給路にインクを供給することが可能なインク連通流路が形成されている。記録素子基板１１０、１１１における幅方向の長さは、支持部材２ａ、２ｂにおける幅方向の長さよりも長い。【選択図】図１１
