An antistatic shoe includes an outsole having a conducting portion that is made of a conducting material and an insole that has a conducting portion mad of a conducting material. An antistatic unit is sewn to the conducting portion of the insole from below so as to be located between the outsole and the insole. An upper is mounted on the outsole and the insole. Electric connection between the components allows static electricity from a human body to be transmitted to a resistor in the antistatic unit, so that static electricity that would otherwise accumulate in the human body can be stably removed by the resistor and sent to the ground. This eliminates the risk of a transient electrostatic discharge that may disadvantageously damage adjacent electronic devices or generate sparks.
