Composite and production method thereof

摘要

There is disclosed a composite comprising a first substrate comprising a formed resin body containing a silicone-modified resin, and a second substrate having a to-be-joined surface joined to a to-be-joined surface of the first substrate,
wherein the to-be-joined surface of the first substrate, or the to-be-joined surfaces of the first and second substrates has/have been subjected to application of one or more of an ultraviolet light irradiating treatment, a corona treatment, and a plasma treatment. As a result, there is provided a composite and an expedient production method of such a composite, which composite comprises a substrate comprising a formed resin body containing a silicone-modified resin, and another substrate joined to the firstly mentioned substrate in a strong manner with excellent durability therebetween.
