To provide a liquid jet head which detects a temperature of liquid flowing through a passage accurately, and to provide a liquid jet device.SOLUTION: A liquid jet head includes: a nozzle which jets liquid; a passage member formed with a passage, communicating with the nozzle, and having an inner wall surface 60 defining the passage and an outer wall surface 70 opposite to the passage with respect to the inner wall surface 60; and a temperature sensor 20 which is disposed at a part of the outer wall surface 70 and detects a temperature of the liquid in the passage. The passage includes a contraction area 55 whose width is narrow in a second direction Z orthogonal to a first direction Y along a direction in which the passage extends. The temperature sensor 20 is disposed at a portion, which forms the contraction area 55, of the outer wall surface 70.SELECTED DRAWING: Figure 6 【課題】流路を流れる液体の温度を精度よく検出する液体噴射ヘッド、及び液体噴射装置を提供する。【解決手段】液体噴射ヘッドは、液体を噴射するノズルと、ノズルに連通する流路が形成され、流路を画定する内壁面６０及び内壁面６０に対して流路とは反対側の外壁面７０を有する流路部材と、外壁面７０の一部に配置され、流路内の液体の温度を検出する温度センサー２０と、を備える。流路は、流路が延在する方向に沿う第１方向Ｙに直交する第２方向Ｚに幅が狭い狭窄領域５５を含み、温度センサー２０は、外壁面７０のうち狭窄領域５５を形成する部分に配置されている。【選択図】図６
