ABSTRACT:
A method of producing a piezoeIectric resonator includes the steps of forming first to third internal electrodes by printing an electrically conductive paste onto a green sheet, punching out portions of the green sheet having the first to third internal electrodes formed thereon, so that at least three types of green sheets are punched out with a location of the internal electrode serving as a reference location, in which the first 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 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 sheet is punched out at the reference location, forming a layered body by stacking the punched out green sheets, and forming a unit by cutting the layered body.
