Title:
METHOD FOR MANUFACTURING PIEZOELECTRIC SENSOR
Document Type and Number:
Japanese Patent JP2014135308
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a method for manufacturing a piezoelectric sensor.SOLUTION: The method for manufacturing a piezoelectric sensor includes: integrally laminating first and second laminate sheets on one surface of a long piezoelectric sheet to manufacture a piezoelectric laminate sheet; piercing a piercing terminal in the piezoelectric laminate sheet to electrically connect a first electrode layer of the first laminate sheet to a third electrode layer of the second laminate sheet; and thereafter cutting the piezoelectric laminate sheet. The first electrode layer of the first laminate sheet is continuous to the length direction of the first laminate sheet. An avoidance section is formed either on a signal electrode pattern or between signal electrode patterns to avoid the piercing terminal. A visible section visible of the avoidance section is formed on the third electrode layer of the second laminate sheet, so that the piercing terminal is pierced in the piezoelectric laminate sheet while the avoidance section is confirmed through the visible section.
