The present invention provides adhesion of a solid to an elastic member with a sufficient adhesive strength. The present invention, specifically, provides a product comprising an elastic member having at least 200% elongation and a solid adhered to the elastic member with a hot-melt adhesive. Specifically, according to the present invention, adhesion of an elastic member and a solid of excellent durability with adhesive force of 2.510.sup.6 Pa or more, more preferably adhesive force of 2.710.sup.6 Pa or more, even more preferably adhesive force of 3.010.sup.6 Pa or more, and particularly preferably adhesive force of 3.510.sup.6 Pa or more, is provided.

A method for preparing a composite body (1) comprising a support body (2) and at least one decorative element (3), preferably a gemstone (3a, 3b), the support body (2) comprising a thermoplastic material, the method being characterized by the steps of: arranging the decorative element (3) on the support body (2), heating the support body (2), pressing the decorative element (3) into the support body (2) by using a stamp (4) consisting of an elastically deformable material, the material of the stamp (4) being selected from the group of elastomers.
