Abstract
In a method for adjusting a fluid control apparatus, in a pressing step, a piezoelectric pump is placed on a stage with a cover plate facing upward, the stage is moved up, and a center portion of a principal surface of the cover plate on a side opposite to a diaphragm is pressed with a pressing pin. As a result, the cover plate and the base plate are shaped so as to warp convexly toward the diaphragm side, and a portion joined to a flexible plate is pulled, such that the flexible plate is caused to warp convexly toward the diaphragm side. Thus, residual tensile stress occurs in a movable portion of the flexible plate. Therefore, due to the residual tensile stress, the tensile stress of the movable portion of the flexible plate is increased.
