Abstract: There are provided a flow channel member, a liquid jet head, and a liquid jet device which prevent generation of bubbles in an ink flow channel, and are excellent in ejection performance. There is included a first flow channel plate provided with a first ink flow channel adapted to communicate an ink tank and a first head chip with each other, the first ink flow channel includes a narrow flow channel located on an upstream side, a filtration flow channel located on a downstream side with respect to the narrow flow channel, and a connecting flow channel adapted to connect the narrow flow channel and the filtration flow channel to each other, and the connecting flow channel gradually increases in flow channel width in a direction from the upstream side toward the downstream side, and decreases in flow channel depth in the direction from the upstream side toward the downstream side.

Abstract: There are provided a flow channel member, a liquid jet head, and a liquid jet device each capable of achieving thickness reduction while ensuring the effective area of a filter. There is included a first flow channel plate provided with a first ink flow channel adapted to communicate an ink tank and a first head chip with each other, the flow channel plate is disposed in a state in which a thickness direction of the flow channel plate crosses a gravitational direction, the first ink flow channel includes a filtration flow channel through which ink flows along the thickness direction of the first flow channel plate, and in which a main filter is disposed, and an upstream flow channel which is communicated with an upstream end of the filtration flow channel, and through which the ink flows along a surface direction of the first flow channel plate, and a reservoir wall part is formed in a part located on a downstream side of the main filter on an inner surface of the filtration flow channel, the reservoir wall part separating between the filtration flow channel and a downstream flow channel, and having a communication flow channel adapted to communicate the filtration flow channel and the downstream flow channel with each other in upper end parts in the gravitational direction.
