A liquid jet head is provided with a first bubble generating device (2) for enabling a first flow path (6) conductively connected with a first discharge opening (4) to create a bubble for the formation of discharge droplet, and a second bubble generating device (3) for enabling a second flow path (7) conductively connected with a second discharge opening (5) to create a bubble for the formation of discharge droplet, and comprises a substrate (1) having the first and second bubble generating devices on the surface area shared by them for use, an orifice section provided with the first and second discharge openings sequentially in the direction intersecting the sharable surface area of the substrate, and a flow path formation section for separating each path of the first and second flow paths at least from the discharge opening to the bubble generating device thereof, at the same time, arranging at least part of the first and second flow paths to be essentially in the form of laminated layer with respect to the substrate. With the structure thus arranged, crosstalks are prevented across each line of liquid flow paths, and also, to materialize a liquid jet head capable of making its discharge amount variable for the stabilized discharge of droplets in different amount from the plural lines of discharge openings for recording images in higher precision and quality. <IMAGE> |
