摘要： The present invention provides a liquid ejecting head in which a chip crack is unlikely to occur. To achieve this, a liquid ejecting head includes an element substrate having energy generating elements arranged on the front face of the element substrate in its longitudinal direction and a channel member having ejection ports formed to correspond to the energy generating elements, respectively. In the element substrate, a supply port for supplying liquid is formed so as to pierce through from a back face to a front face of the element substrate, and inside the supply port, a beam is formed at a position closer to an end of the supply port rather than a center thereof in its longitudinal direction to connect facing inner walls of the supply port in its lateral direction.

摘要： A method for manufacturing a liquid discharge head. The method includes a first step of forming a telecentric measurement pattern A by exposure, the telecentric measurement pattern A being part of a measurement pattern that allows determination of inclination of a principal ray caused by an off-axis telecentric degree occurring in a projection exposing device, and a second step of forming a telecentric measurement pattern B by exposure under an exposure condition defocused from an exposure condition in the first step, the telecentric measurement pattern B being another part of the measurement pattern, which allows the determination of the inclination of the principal ray caused by the off-axis telecentric degree occurring in the projection exposing device. The off-axis telecentric degree is determined from an amount of misalignment between relative forming positions of the telecentric measurement patterns A and B and an amount of defocusing.

摘要： Provided is a method of manufacturing a liquid ejection head, including: forming, on a substrate, a flow path mold pattern that becomes a mold of a liquid flow path; forming a negative photosensitive resin layer on the flow path mold pattern; subjecting the negative photosensitive resin layer to exposure processing with use of a reduction projection exposing apparatus and a mask pattern having an ejection orifice mask shape for forming ejection orifices; and subjecting the negative photosensitive resin layer obtained after the exposure processing to development processing to form the ejection orifices, in which the ejection orifices are formed by correcting, by the ejection orifice mask shape, an inclination of an ejection angle due to an off-axis telecentricity caused by the reduction projection exposing apparatus so as to be close to a direction perpendicular to a surface of the substrate.
