An electrostatic precipitation module includes a plurality of conductive precipitation electrode plates and a plurality of non-precipitation electrode plates. The plurality of precipitation electrode plates are interlacedly distributed along the length of a first connecting rib; the precipitation electrode plates are made from conductive plastic material by injection molding, and a metal conductor is embedded inside the first connecting rib by in-mold injection molding, so that a precipitation electrode plate module is formed; a non-precipitation electrode plate module is formed with a similar structure. After the precipitation electrode plate module and the non-precipitation electrode plate module are assembled, the precipitation electrode plates and the non-precipitation electrode plates form an electrostatic precipitation module. Together they form an electrostatic air purifier using the electrostatic precipitation modules which can be assembled quickly, improves the uniformity of electric field distribution and has excellent electrostatic absorption performance.
