Liquid ejecting head and liquid ejecting apparatus

A liquid ejecting apparatus, comprising:

• a liquid ejection head configured to eject a liquid, the liquid ejection head including:
• a piezoelectric member formed of a piezoelectric material, the piezoelectric member having a plurality of grooves extending lengthwise in a first direction, the grooves separating portions of the piezoelectric member into a plurality of piezoelectric elements spaced from each other in a second direction, a connection portion of the piezoelectric member being under at least a portion of the grooves in a third direction, the connection portion connecting the plurality of piezoelectric elements to each other;
• a substrate joined to the connection portion of the piezoelectric member;
• individual electrodes on a first surface of the piezoelectric member on a first side;
• and
• a common electrode on a second surface of the piezoelectric member on a second side, wherein
• each groove has a depth in an end portion of the groove on the first side that is deeper than a depth in an end portion of the groove on the second side, and
• the depth of each groove in the end portion on the first side reaches through the piezoelectric member to the substrate.
