Abstract
There are provided a liquid jet head and a liquid jet recording device each capable of obtaining a stable ejection performance. An inkjet head includes a head chip provided with a plurality of ejection channels sequentially arranged from a +X direction toward a −X direction in an X direction, and configured to jet ink located inside the ejection channels, a flow channel member which is provided with a guide flow channel for guiding the ink from the +X direction toward the −X direction in the X direction, and in which the guide flow channel is coupled to each of the ejection channels, and a board unit on which a plurality of drive ICs arranged along the X direction is mounted, and which is thermally coupled to the flow channel member, wherein the flow channel member is provided with a cooling flow channel which guides the ink from the −X direction toward the +X direction in the X direction so as to cool the plurality of drive ICs.
