Zusammenfassung:	According to one embodiment, a liquid ejection head, includes a piezoelectric member having grooves extending lengthwise in a first direction. The grooves separate the piezoelectric member into piezoelectric elements spaced from each other in a second direction. A connection portion of the piezoelectric member is under a portion of the grooves in a third direction and connects the piezoelectric elements to each other. Individual electrodes are on a first surface of the piezoelectric member on a first side. A common electrode is on a second surface of the piezoelectric member on a second side. Each groove has a depth on the first side that is deeper than a depth in an end portion on the second side. The depth of each groove in the end portion on the first side reaches through the piezoelectric member to a substrate.
