ABSTRACT:
A method for producing an elastic plate for a liquid jet head, which includes etching a rolled metal plate based on a rolling direction of the rolled metal plate, to form an etched portion and a non-etched portion on the rolled metal plate. The thickness of the etched portion is thinner than the thickness of the non-etched portion and the rolling direction is substantially perpendicular to a long side of the rolled metal plate.
