Method of producing multilayer piezoelectric resonator

A method of producing a multilayer piezoelectric resonator, the method comprising the steps of:

• forming internal electrodes by printing an electrically conductive paste onto a surface of a green sheet formed of piezoelectric ceramic;
• punching out portions of the green sheet having the internal electrodes formed thereon with certain sizes, so that at least three types of green sheets including a first green sheet, a second green sheet, and a third green sheet, are punched out with a particular location of each respective corresponding internal electrode serving as a reference location, in which the first green sheet is punched out by shifting a punching location by a first shift amount in a first direction with respect to the reference location, the second green sheet is punched out by shifting a punching location by the first shift amount in a direction opposite to the first direction, and the third green sheet is punched out at the reference position;
• forming a layered body by placing the punched out green sheets upon each other in a predetermined order;
• forming a unit by cutting the layered body, with the cutting operation being performed so that the internal electrode formed on the first green sheet and the internal electrode formed on the second green sheet are exposed at opposing end surfaces of the unit, and so that the internal electrode formed on the third green sheet is not exposed at an end surface of the unit;
• and
• forming a ceramic sintered body by baking the unit formed by the cutting operation.
