The droplet discharge head comprises: a plurality of nozzles which discharge droplets of liquid; a plurality of pressure chambers which are connected to the nozzles and filled with the liquid to be discharged through the nozzles; and a laminated piezoelectric body which has a plurality of active portions to impart pressure variation to the liquid inside the pressure chambers so as to cause the droplets to be discharged from the nozzles, respectively, wherein first linear grooves and second linear grooves which intersect each other at a prescribed non-orthogonal angle are formed in the laminated piezoelectric body, and the active portions of the laminated piezoelectric body are defined by the first and second linear grooves.
