Layers are thermally bonded with each other while retaining a 3D conformation of fibers of nonwoven fabrics made of synthetic resin, by heating at a heatproof temperature or higher, using a vapor of water or a nonaqueous solvent in a high-pressure steam sterilizer or a high-pressure steam pot. Then, three nonwoven fabrics made of synthetic resin which consist of different materials are superposed to form three layers, and can be thermally bonded together by heating at the heatproof temperature or higher, using the high-pressure steam sterilizer. A laminated body 10 has layers thermally bonded together while retaining a 3D conformation of fibers of each of a nonwoven fabric A made of synthetic resin (referenced 11), a nonwoven fabric B made of synthetic resin (referenced 12) and a nonwoven fabric C made of synthetic resin (referenced 13). |
