摘要： A liquid discharge cartridge manufacturing method includes a first step of individually shaping a first shaped member and a second shaped member that form a housing of a liquid discharge cartridge, and a second step of joining the first shaped member and the second shaped member to be bonded to each other with molten resin. The first step includes shaping a wall section in the first shaped member, the wall section forming a recess for accommodating the molten resin, and shaping a projection in the second shaped member, the projection extending such that the projection is located at the outer side of the wall section and adjacent to the wall section, with a predetermined gap being formed between the projection and the wall section, when the first and second shaped members are joined.

摘要： A print element substrate is absorbed and held by a handling jig to define a predetermined location and position of the print element substrate with respect to the supporting member. In this instance, the handling jig is provided with a convex portion. Therefore, when the print element substrate is joined to the supporting member, the convex portion comes into contact with a surface of the supporting member, so that it is possible to define the height of the print element substrate with respect to the joining surface. This makes it possible to control the amount and height of squash by the print element substrate exerted on the adhesive agent applied on the joining surface. It is possible to prevent the redundant adhesive agent from spilling out in a print liquid flow path.
