LIQUID JET HEAD, LIQUID JET RECORDING DEVICE, AND METHOD OF MANUFACTURING LIQUID JET HEAD

An occurrence of leakage is prevented. An inkjet head jets ink. The inkjet head is provided with a head main body, a cooling pipe, a jet-side coupling member, and a cooling-side coupling member, wherein the head main body has a jet flow path through which the ink passes, the cooling pipe has a cooling flow path through which the ink passes as a cooling medium for cooling a drive circuit, the jet-side coupling member is coupled to the head main body, a jet-side branch path branches from an ink flow path into which the ink inflows from an outside of the inkjet head, or from which the ink outflows, the jet-side branch path is communicated with the jet flow path, the jet-side branch path is provided to the jet-side coupling member, and the cooling-side coupling member is coupled to the jet-side coupling member, and is provided with a cooling-side branch path which branches from the ink flow path, and which is communicated with the cooling flow path. The cooling-side coupling member has a coupling surface along one surface of the jet-side coupling member, and along a direction perpendicular to the cooling pipe.
