The invention discloses an electrostatic protection device in the technical field of semiconductor electrostatic protection, and aims to solve the problem of poor robustness of an electrostatic protection device in the prior art. After a first terminal and a second terminal are connected to a circuit needing electrostatic protection, when any end of the first terminal and the second terminal encounters electrostatic pulses, a polar plate of a capacitor generates electron migration, due to the fact that the electrostatic generation time is extremely short, the electron migration can be regarded as short circuit of the capacitor, and the first terminal and the second terminal at the two ends are conducted through a carbon nano tube; an electrostatic pulse escapes from a circuit needing electrostatic protection through a path formed by the first terminal, the carbon nano tube and the second terminal and flows away from the power supply port; when no electrostatic pulse exists, the capacitor blocks direct current
