Abstract
A layer of base material has a film layer and a barrier layer on the film layer, and also adhesive tape has the base material and an adhesive layer on the barrier layer. Thus, they do not have any fish-eye or foreign substance on their surfaces, so that accuracy in thickness are improved and contamination of a material to be adhered with the adhesive layer is also improved.
