To reduce oscillation or ringing of deflection voltage.
The electron beam equipment comprises an electron gun 201 irradiating an electron beam 200, a first shaping deflector 212 and a second shaping deflector 214 for deflecting the electron beam 200 irradiated from the electron gun 201, a deflection amplifier 324 for applying a deflection voltage in parallel with the first shaping deflector 212 and a second shaping deflector 214, and a damping resistor 230 connected with a single core cable 220 for connecting the first shaping deflector 212 and the second shaping deflector 214 and applying a deflection voltage. Since an undulation component can be attenuated, ringing and oscillation are reduced and response characteristics can be enhanced. As a result, precision of deflection can be enhanced. Furthermore, since response characteristics can be enhanced by reducing ringing and oscillation, settling time can be shortened resulting in shortening of the writing time.
