When the vibration frequency of the piezoelectric elements (4) and (5) is set to 1 KHz or more, the outer blade (2) also vibrates equal to the displacement of the piezoelectric element, but the vibration amplitude of the skin in contact with the outer blade can be seen from FIG. When the vibration frequency of the outer cutter (2) increases, the frequency decreases. In particular, when the vibration frequency exceeds 1 KHz, the amplitude of the skin becomes about 1/2.
Therefore, the electric razor in which the outer blade (2) is finely vibrated at a frequency of 1 KHz or more by the piezoelectric element of the present invention allows the beard to be efficiently introduced into the introduction hole of the outer blade and reduces the vibration of the skin due to the fine vibration of the outer blade. It is possible to suppress shave up to the same level as when the outer blade is not vibrated.
