Abstract:
A liquid jet head provided with a first bubble generating device for enabling a first flow path conductively connected with a first discharge opening to create a bubble for formation of a first discharge droplet, and a second bubble generating device for enabling a second flow path conductively connected with a second discharge opening to create a bubble for formation of a second discharge droplet, said head comprising:a substrate having said first and said second bubble generating devices on a shared surface area;an orifice section provided with said first and said second discharge openings sequentially in a direction intersecting said shared surface area of said substrate; anda flow path formation section for separating from one another each of the first and the second flow paths, each of the flow paths being separated at least from the discharge opening corresponding thereto to the bubble generating device corresponding thereto, at least part of said first and said second flow paths being arranged so that the first flow path is disposed in a first layer adjacent to said substrate and said second flow oath is disposed in a second layer adjacent to said first layer.
