<P>PROBLEM TO BE SOLVED: To provide a vibrator that can be manufactured more simply. <P>SOLUTION: A vibrator is a laminate in which a plurality of piezoelectric substances 22 having an electrode provided on an upper-surface and under-surface are laminated in a state where these are shifted in a plane direction, and the vibrator comprises: a laminate with an electrode layer 24 formed on the upper surface and the under-surface of the laminate and between piezoelectric substances by the electrode; a ground electrode 30 arranged on the upper-surface of the laminate; a signal electrode 32 arranged on the under-surface of the laminate; and a plurality of anisotropic conductive substances 28 arranged in a posture in which conductivity is exerted only in a laminating direction. The anisotropic conductive substance 28 is arranged between an exposed portion of the electrode layer 24 exposed outside due to being laminated with the piezoelectric substance 22 shifted and any one of exposed portions of the ground electrode 30, signal electrode 32 and other electrode layers 24, and thereby, electrically connects integrally both the even-numbered electrode layers 24-2 and 24-2, and both the odd-numbered electrode layers 24-1 and 24-3. <P>COPYRIGHT: (C)2012,JPO&INPIT |
