A cell bursting method of a plastic foam sheet includes steps of producing a foam sheet and carrying on vacuum cell bursting to the foam sheet. In the process of the vacuum cell bursting, air in the cells of the foam sheet inflates to expand their cell walls to a preset extent, and the instant when normal pressure recovers, the cell walls burst instantly due to rapid releasing of pressure, able to produce a plastic foam sheet having high flexibility, good permeability and excellent elasticity.
