The invention discloses a pinhole array miniature electrostatic electric thruster. The pinhole array miniature electrostatic electric thruster comprises a neutralizer and a thruster body which are mutually connected, wherein the thruster body sequentially comprises a grid component, a pinhole array component and a propellant storage chamber which are cooperatively connected from top to bottom; the pinhole array component is formed by conveying plates and a pinhole array plate; the conveying plates are arranged on the lower surface of the pinhole array plate; pinhole arrays are uniformly distributed in the pinhole array plate; the grid component consists of an extraction grid, an acceleration grid and an insulation bracket; the extraction grid, the acceleration grid and the pinhole array plate are sequentially connected through the insulation bracket; and coaxial pinholes corresponding to the pinhole arrays are formed in the extraction grid and the acceleration grid; and heaters and the propellant are all located in the propellant storage chamber. The pinhole array miniature electrostatic electric thruster has the advantages that the structure is simple; the size is small; the specific impulse can reach 700-2000 s; the propellant storage function and the conveying function are integrated; the propellant is stored in a pressure-free mode; no movable components exist; and the like. The pinhole array miniature electrostatic electric thruster can be packaged in a chip mode, and can be applied to microsatellites as a standard thrusting module.
