Abstract
An osmosis membrane is disposed at the boundary between a three-dimensional network structure section and a foam section. The osmosis membrane allows a liquid foam material to permeate. The three-dimensional network structure section is impregnated with the foam material through the osmosis membrane, and subsequently the foam material is solidified, thereby connecting the three-dimensional network structure section and the foam section to each other. The bonded body of the three-dimensional network structure section and the foam section is completed only by disposing the cushion structure component in between the upper mold and the lower mold, and performing a foaming step.
