PROBLEM TO BE SOLVED: To adequately prevent, with a simple configuration, a medium from coming in contact with a jet surface on which nozzles jetting a liquid are provided.SOLUTION: A liquid jet head 26 comprises: a jet surface 262 on which a plurality of nozzles jetting ink are distributed; and protrusions 40 provided in a long shape on the jet surface, and protruding from the jet surface. Each protrusion includes a portion with a different height from one end side to the other end side. The width of the protrusion is narrower from a root side to a tip end side in a height direction, and one end part 42a of the protrusion is different from the other end part 42b in shape. This prevents a medium from coming into contact with the jet surface with a simple configuration since the protrusions can suppress floating of the medium even when the medium 12 which is conveyed facing the jet surface is curled.SELECTED DRAWING: Figure 6 |
