Abstract:
A method of producing an ink jet recording head, comprising the steps of:(a) forming a nozzle communicating hole through which a pressurizing chamber is communicated with a nozzle opening, by anisotropic etching performed on both faces of a silicon single-crystal substrate; (b) after said through hole is formed, forming a recess which will serve as the pressurizing chamber, by half etching performed on one of the faces of said silicon single-crystal substrate; and (c) fixing an elastic plate to a face of said silicon single-crystal substrate in which said through hole and said recess are formed in the previous steps, said face being on the side of said recess which will serve as said pressurizing chamber, and fixing a nozzle plate to another face.
