A laminated structure in which interconnections can be easily formed for electrodes and in which the damage of an insulating layer attributed to stress is relieved. The laminated structure includes a laminated piece having a first electrode layer provided with a first insulating region, a piezoelectric material layer, and a second electrode layer provided with a second insulating region at a position different from that of the first insulating region, a first interconnection line electrically connected to the first electrode layer while passing through the second insulating region provided in the second electrode layer, and a second interconnection line electrically connected to the second electrode layer while passing through the first insulating region provided in the first electrode layer.
