PROBLEM TO BE SOLVED: To provide a liquid jet head capable of preventing an electrode wire from being disconnected when a temperature sensor is bent at an unexpected portion.SOLUTION: A liquid jet head 10 comprises: a temperature sensor 1 which comprises a flexible substrate 2 having an electrode wire 3 that extends from a position in front of one end Ea in a longer direction to another end Eb side, and a temperature detection element 4 which is located in front of the one end Ea of the flexible substrate 2 and is electrically connected to the electrode wire 3; and a liquid compression plate comprising a plurality of channels. In terms of flexural rigidity for bending the flexible substrate 2 in the longer direction in a vicinity region R of the temperature detection element 4, a vicinity region Ra on the one end Ea side is smaller than a vicinity region Rb on the other end Eb side.SELECTED DRAWING: Figure 1 |
