PROBLEM TO BE SOLVED: To provide a suction nozzle capable of holding a piezoelectric vibration element in a regular posture on a suction surface when it is sucked even when the fixed posture of the piezoelectric vibration element is dispersed when supplying a negative pressure from vent holes provided on the suction surface of the suction nozzle and sucking and holding the upper surface of the roughly horizontally fixed piezoelectric vibration element, and to provide an automatic mounter, a loading method of the piezoelectric vibration element, a piezoelectric vibrator and a piezoelectric oscillator. SOLUTION: The suction nozzle is provided with the suction surface 31 for sucking and holding one surface of the piezoelectric vibration element 20 and the vent holes 32 and 33 formed on the suction surface for supplying a negative pressure for sucking the piezoelectric vibration element. A stopper 35 projected to the suction surface side so as to abut the distal end edge of the piezoelectric vibration element is provided on the distal end edge of the suction nozzle. On the sidewall 35a of the stopper abutted to the distal end edge of the piezoelectric vibration element, the vent hole 36 for supplying the negative pressure for sucking the distal end edge of the piezoelectric vibration element is formed.
