Abstract: A liquid discharge head includes a discharge chip including a discharge port for discharging liquid, and a cover member having an opening for exposing the discharge chip, the cover member including a first surface which is joined to the discharge chip with adhesive, and a second surface opposite from the first surface, wherein, at least in a part of the opening as viewed from a direction perpendicular to the second surface, an edge on the second surface side is positioned inside the opening with respect to an edge on the first surface side.

Abstract: A joining method includes the steps of applying a first adhesive in a line shape to a joining area of a first substrate, applying a second adhesive in a broken line shape to the joining area of the first substrate, at a predetermined interval from the first adhesive layer in the line shape, to form multiple second adhesive layers with a gap formed due to the broken line shape, bonding the second substrate to the first substrate with the first adhesive layer and the multiple second adhesive layers and pressure-bonding the second substrate to the first substrate, curing the multiple second adhesive layers between the first substrate and the second substrate pressure-bonded, and curing the first adhesive layer after the multiple second adhesive layers are cured.

Abstract: The object is to provide a liquid container that can prevent foreign substances from flowing into a liquid ejection apparatus with a simple configuration. The liquid container for containing liquid to be ejected by a liquid ejection apparatus, the liquid container includes a bag body configured to contain the liquid inside and a flow path for supplying the liquid contained inside the bag body to the liquid ejection apparatus, wherein, a first capturing unit extending in an anti-gravitational direction or a second capturing unit extending in a gravitational direction is arranged inside a peripheral wall of the flow path.

Abstract: The liquid storage unit includes a rectangular parallelepiped case having an open upper surface and a liquid storage pack including a rectangular parallelepiped adapter. The liquid storage pack is detachably housed in the case, the case includes a convex portion that protrudes from the inner side surface along a first direction perpendicular to a bottom surface, the adapter includes a concave portion that is formed on the outer side surface along a first direction and open to the lower surface, and the concave portion can engage with the convex portion in a second direction perpendicular to the first direction and parallel to the inner side surface, and is formed asymmetrically with respect to a surface that passes through the center of the adapter in the first direction and is perpendicular to the first direction.

Abstract: The object is to provide a liquid container capable of supplying liquid to a liquid ejection apparatus with simple configuration. Liquid container 100 has liquid containing bag 120 and an introduction member. The introduction member includes the first and second liquid introduction members. The first introduction member has the first spacer unit and the first coupling unit integrally connected to the first spacer unit in which the first groove for letting liquid flow to a liquid lead-out unit is formed. The second introduction member has the second spacer unit and the second coupling unit integrally connected to the second spacer unit in which the second groove for letting liquid flow to the liquid lead-out unit is formed. The first and second liquid introduction members are adjoined so that the surface on which the first groove is formed and the surface on which the second groove is formed face each other.
