Liquid ejection head and liquid ejection apparatus

A liquid ejection head comprising:

• a vibration plate sealing a plurality of pressure generating chambers that communicate with nozzles through which liquid is ejected;
• a case head that is mounted on the vibration plate;
• piezoelectric elements that are mounted on the case head;
• and
• a fixation member bonded to the piezoelectric elements,
• wherein one face facing the vibration plate side of the fixation member is adhered to the case head by using a first adhesive and a second adhesive, and the piezoelectric elements are bonded to the fixation member at a surface that is transverse to the one face of the fixation member and wherein the piezoelectric elements are also attached to the vibration plate,
• wherein:
• the first adhesive has adhesion strength higher than an adhesion strength of the second adhesive and the first adhesive is applied on a first adhesive surface on the one face of the fixation member overlapping the piezoelectric elements in an arrangement direction of the piezoelectric elements, the second adhesive has curing time shorter than a curing time of the first adhesive and the second adhesive is applied on a second adhesive surface on the one face of the fixation member does not overlap with the piezoelectric elements in the arrangement direction of the piezoelectric elements.
