PROBLEM TO BE SOLVED: To provide a vibrating table advantageously usable for machining a workpiece of small size. SOLUTION: This vibrating table is constituted by fixing a piezoelectric vibrator of plate shape to the lower side surface of a metal table, and the piezoelectric vibrator of plate shape comprises: a piezoelectric body of plate shape formed by joining four or more longitudinal columnar piezoelectric bodies through a resin material at the mutually adjacent side faces of the respective columnar piezoelectric bodies; and electrode layers provided at the upper and lower surfaces of the piezoelectric body of plate shape.
