Abstract

A packing box for an electronic product to protect an electronic product from external impact. The packing box includes a first packing unit to pack an upper part of the product, a second packing unit passing through the first packing unit and joined to a lower part of the first packing unit, to pack a middle part of the product, and a third packing unit passing through the first and second packing units and joined to a lower part of the second packing unit, to pack a lower part of the product. The packing box is readily disassembled and allows the product to be easily repacked.
