Provided is a detachable-type automatic electron needle having an electric current generating unit, thereby enabling a user to conveniently use the electron needle by separating a portion of supplying an electric current and a portion of fixing the electron needle. The detachable-type automatic electron needle includes an electric current generating unit, an electron needle fixing plate(300) having at least one electron needle receiving port, and plural electron needles(510) inserted into the electron needle receiving port of the electron needle fixing plate. The electric current generating unit has a cylindrical grip(100), a reduction motor(110) fixed to the grip for rotating a rotor shaft by supplying an electric power, a cam(120) engaged to the rotor shaft, a bearing(121) engaged to an outer peripheral surface of the cam, a piezoelectric unit(200) fixed to one portion of the fixing plate for generating an electric current by piezoelectric effect according to a rotation of the cam, and a support(400) fixed to the other portion of the fixing plate.
