    Abstract: A liquid discharge head includes a recording element substrate for discharging a liquid and a housing with the recording element substrate attached thereto. A plurality of holes having openings on a back side of an attachment surface of the housing to be attached to the carriage, are juxtaposed in a direction intersecting with a vertical direction in a state where the liquid discharge head is attached to the carriage. Two positioning bosses, on the attachment surface, are formed above two holes at both end sides of a plurality of the juxtaposed holes or above portions on an inner side than the two holes, and configured to contact the carriage to determine a position of the liquid discharge head on the carriage.

    Abstract: A manufacturing method of a liquid ejection head includes a step of performing a first exposure to form a first ejection orifice row and a step of performing a second exposure to form a second ejection orifice row in which ejection orifices are arranged in a row with ejection orifices that form the first ejection orifice row through a connection portion. In an ejection orifice row formed by the first and the second ejection orifice rows, regarding the distances between the centers of ejection orifices in an arrangement direction of the ejection orifices on opening surfaces of the ejection orifices, the ejection orifices are formed so that a distance between the centers of two ejection orifices adjacent to each other with the connection portion in between is longer than a distance between the centers of two ejection orifices adjacent to each other without the connection portion in between.
