The present invention relates to an antistatic structure for an optical disc device. An optical pick-up unit module of an optical disk device is installed on a chassis and the chassis is movably installed in a lower cover of the device. Furthermore, the antistatic structure includes at least one upper connecting portion capable of contacting with the optical pick-up unit module and at least one lower connecting portion capable of contacting with the lower cover. Whereby, the static electricity generated by the optical pick-up unit module can be conducted to the lower cover through the upper and lower connecting portions so as to attain the antistatic discharge (ESD) protection effectively.
