Method of manufacturing liquid ejection head

摘要

A support substrate and a liquid ejecting element substrate are bonded to each other with an adhesive agent to manufacture a liquid ejection head. The support substrate is provided with a liquid supply port and a recess or through-hole in its main surface. The adhesive agent is applied onto the main surface of the support substrate by means of a roller holding the adhesive agent on its peripheral surface by moving the support substrate and the roller relative to each other such that the recess or through-hole faces the roller before the liquid supply port faces the roller.

1. A method of manufacturing a liquid ejection head, comprising:
a step of preparing a support substrate provided with a plurality of liquid supply ports for supplying liquid and a plurality of recesses or through-holes in a main surface thereof, the plurality of liquid supply ports being arranged in a zigzag arrangement on the main surface; a step of transferring an adhesive agent onto the main surface by effecting relative movement between the support substrate and a roller holding the adhesive agent so as to make the recess or through-hole face the roller before the liquid supply port faces the roller; and a step of bonding, using the adhesive agent, the support substrate and a plurality of recording element substrates having energy generating elements for ejecting liquid, wherein the dimension of the recess or through-hole is greater than the dimension of the liquid supply port in a direction orthogonal to the direction of the relative movement between the roller and the support substrate.
