PROBLEM TO BE SOLVED: To provide a liquid jet head which prevents moisture evaporation from an adhesion part of a holding member and a liquid jet head main body, enhances adhesion strength of the holding member and the liquid jet head main body, and also facilitates position management of a nozzle surface of the liquid jet head main body, and to provide a liquid jet device.SOLUTION: A liquid jet head includes: a holding member 14 having a liquid introduction channel 21; a liquid jet head main body 15 which introduces a liquid to a pressure chamber 36 through a liquid channel 51 and can discharge as liquid droplets from a nozzle 38; and a fixing plate 16 on which the liquid jet head main body is fixed. The fixing plate includes a first junction part 53 to which a nozzle surface 39 is joined, and a second junction part 54 to which the holding member is joined. The holding member has a housing space 22. A periphery of a communication part of the liquid introduction channel and the liquid channel is adhered in a state that the liquid jet head main body, of which the nozzle surface is joined to the first junction part of the fixing plate, is housed in the housing space, and the second junction part of the fixing plate and an opening peripheral edge part of the housing space of the holding member are joined.SELECTED DRAWING: Figure 5 |
