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 |
