Abstract

A method for manufacturing a liquid jet recording head comprises the steps of coating a path wall forming member on a solid layer disposed on a substrate plate and having a liquid path pattern communicating with liquid discharge openings, binding a lid plate to the substrate plate via the path wall forming member, and removing the solid layer, thereby forming liquid paths. In the binding step the lid plate is bound to the substrate plate via spacer means having a thickness greater than that of the solid layer and disposed at an area which does not correspond to the path pattern and via the path wall forming member, while applying a pressure toward a binding position.
