Abstract: 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.

Abstract: A flow rate distribution of flow paths is controlled. An inkjet head jets ink. The inkjet head is provided with a head main body having a jet flow path through which the ink passes, a cooling pipe having a cooling flow path through which the ink passes as a cooling medium for cooling a drive circuit, and a throttle member for controlling a flow path resistance of the cooling flow path.

Abstract: A cooling efficiency is increased. An inkjet head is provided with a head main body for jetting ink, a cooling pipe which has corrosion resistance to the ink, and through which the ink for cooling a drive circuit passes, and a cooling member which has higher thermal conductivity than that of the cooling pipe, in which at least a part of the cooling pipe is embedded, and which has recessed parts in at least a part of a portion surrounding the cooling pipe.
