An ultra-thin corona sterilization module is related, including an insulation enclosure, a apertured negative electrode plate and a positive electrode holder, the apertured negative electrode plate is at the bottom of the insulation enclosure and has many mounting holes for mounting cylinder-shaped tubes. Each cylinder-shaped tube has a bottom air inlet fixed in the mounting hole, and a top opening as an air outlet. The positive electrode holder is grid-shaped, positioned at the top of the insulation enclosure and spaced apart from the air outlet, with an electrode needle suspended above axis center of each metal cylinder-shaped tube. The electrode needle's end is at a skeleton of the positive electrode holder. The electrode needle's tip is spaced 5-10 mm from the air inlet. The disclosure applies electrostatic catalytic technology to air sterilization by generating a corona field through high voltage electrostatic, thus achieving air sterilization in a manned environment.
