Abstract
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 and the liquid supply port sequentially face the roller in this order.

A method of manufacturing a liquid ejection head comprising:
- a step of preparing a plate substrate having a surface provided with an aperture for supplying liquid and a recess or through hole;
- and
- a step of rotating a roller holding an adhesive agent on a peripheral surface thereof and transferring the adhesive agent onto the surface of the plate substrate;
- the recess or through hole and the aperture being arranged in this order as viewed in the transfer direction.
A plate substrate comprising:
- a surface for receiving an adhesive agent held by a roller so as to be transferred thereto;
- an aperture formed in the surface, for supplying liquid;
- and
- a recess or through hole formed in the surface;
- the recess or through hole and the aperture being arranged in the surface in this order as viewed in the transfer direction.
