PROBLEM TO BE SOLVED: To provide a liquid jet head which accurately detects a temperature of a liquid and achieves improvement of the recording quality, and to provide a liquid jet device.SOLUTION: A liquid jet head includes: a discharge part which discharges ink; a supply joint 35 which is connected with an ink tank through an ink supply pipe and has a discharge supply passage 82 communicating with the discharge part; an ink contact member 93 which is formed by a material having heat conductivity higher than that of the supply joint 35, inserted into the supply joint 35, and forms a part of an inner peripheral surface of the discharge supply passage 82; and a temperature sensor 92 which detects an ink temperature through the ink contact member 93. A recessed part 96 enclosing the temperature sensor is formed in the ink contact member 93.SELECTED DRAWING: Figure 6 【課題】液体の温度を正確に検出し、記録品質の向上を図ることができる液体噴射ヘッド及び液体噴射装置を提供する。【解決手段】インクを吐出する吐出部と、インク供給管を介してインクタンクに接続されるとともに、吐出部に連通する吐出用供給流路８２を有する供給ジョイント３５と、供給ジョイント３５よりも熱伝導率の高い材料からなり、供給ジョイント３５に差し込まれて吐出用供給流路８２の内周面の一部を構成するインク接触部材９３と、インク接触部材９３を介してインク温度を検出する温度センサ９２と、を備え、インク接触部材９３には、温度センサを内包する凹部９６が形成されていることを特徴とする。【選択図】図６
