ABSTRACT:
An elastic permeable material and method of making same involves a board-like basic structure made of a foam material having therein close cells. The basic structure is provided with a plurality of recesses which are filled with an emulsified foam body having therein open cells. The basic structure is subjected to a heating and then a curing before the top and the bottom layers of the basic structure are peeled off so that the recesses become through holes. The basic structure is used as a main framework while the foam bodies embedded in the through holes form a permeable framework. The elastic permeable material is provided thereon a permeable outer covering adhered thereto. The basic structure is heated under a pressure so as to bring about a reduction in the thickness of the basic structure, thereby resulting in a formation of corrugated surface of the elastic permeable material.
