Abstract
Provided is a method for manufacturing a liquid ejecting head which includes a plurality of chips, each of which includes a plurality of segments, each segment including a pressure generating chamber communicating with a nozzle opening through which liquid is discharged, a diaphragm which is a portion of the pressure generating chamber, and a pressure generating unit causing a pressure change in the pressure generating chamber through the diaphragm, the method including measuring natural frequencies of the plurality of segments included in each of the chips, classifying the chips into ranks using the mode value of the natural frequencies of the chips as a reference, and manufacturing the liquid ejecting head which includes the chips selected based on the ranks.
