<P>PROBLEM TO BE SOLVED: To provide a green laminate in which deformation is hard to occur on a plurality of ceramic sheets (piezoelectric sheet) and the thickness of a plurality of ceramic layers (piezoelectric layer) obtained after baking is uniform. <P>SOLUTION: The green laminate is such a laminate as to be a piezoelectric device after baking, in which n (n is integer of three or larger) pieces of plate-like piezoelectric sheets of piezoelectric materials, (n-1) pieces of plate-like internal electrodes, and n pieces of plate-like adhesive layers are stacked in a stacking direction. The piezoelectric sheet is positioned as a top layer and a bottom layer respectively. N pieces of "junction part" (a junction body containing one piezoelectric sheet and one adhesive layer) are distributed to be separated from each other along the stacking direction. Each of (n-1) internal electrodes is positioned to be sandwiched between two "junction parts" adjoining each other. Only one specific internal electrode X among (n-1) internal electrodes is positioned to be sandwiched between two adhesive layers. <P>COPYRIGHT: (C)2013,JPO&INPIT |
