PROBLEM TO BE SOLVED: To provide a liquid droplet discharge head which, when an end face of a partition-shaped projection part formed projecting from one of a plurality of members facing each other is coated with an adhesive and joined to another member while preventing deterioration of rigidity, can suppress squeeze-out of the adhesive during the joining even when the adhesive applied to an end of the end face of the projection part of the one member forms a lump, and to provide a liquid droplet discharge cartridge and an image formation apparatus equipped with the liquid droplet discharge head.SOLUTION: There is provided a liquid droplet discharge head 80 including a holding substrate 40 where a holding substrate partition 42 having an end face to be joined to an individual liquid chamber substrate 10 by applying an adhesive 31 is formed. The liquid droplet discharge head has an excessive adhesive storage part 42a, where an excessive adhesive 31 applied to the end face of the holding substrate partition 42 is stored, at one end of the holding substrate partition 42 in a shorter direction. The excessive adhesive storage part 42a has its cross-sectional shape in the shorter direction of the holding substrate partition 42 made asymmetrical about the center of the holding substrate partition 42 in the shorter direction. |
