To provide an orifice plate for jetting liquid in which in order to reduce a variation in the flow rate of liquid jetted from the orifice plate for jetting the liquid provided in a liquid jetting device or the like so as to stabilize the flow rate of the liquid, for example, the size of shear drop formed on the cut end face of the orifice plate is uniformized along the cutting outline.
The orifice plate for jetting the liquid is made of stainless steel having fine grain structure in which average crystal diameter is ≤3 μm and has the cut end face punched by shearing work. Use of such a fine grain material reduces absolute value of the variation in the size of the shear drop due to a variation in clearance in the piercing work. As a result, the variation width of the cutting outline of fine holes is reduced to thereby lessen the variation in the flow rate of the liquid jetted from the orifice plate.
