Conventional methods using thermosetting adhesives as described above have had the problem of poor heat transfer efficiency for curing the adhesive. In particular, when plastic is used as the substrate, the heat applied from the surface is limited to below the heat-resistant temperature of the plastic, so that the adhesive in the center may not be sufficiently cured.
