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.

Claim (Index 1):
A flow channel member comprising:\n a flow channel plate provided with a liquid flow channel adapted to communicate a supply source of liquid and a head chip with each other, wherein the liquid flow channel includes\n a narrow flow channel located on an upstream side, \n a wide flow channel located on a downstream side with respect to the narrow flow channel, and \n a connecting flow channel adapted to connect the narrow flow channel and the wide flow channel to each other, and \n 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.
