Abstract
A piezoelectric element is attached to a diaphragm via a relay member. A length of the relay member is shorter than the length of the piezoelectric element and longer than an active section in the piezoelectric element with respect to a direction orthogonal to a direction in which a plurality of nozzles are aligned. Also, a surface of the relay member that attached to the diaphragm has a width that is shorter than the piezoelectric element with respect to the direction in which the nozzles are aligned.
