Abstract

The objective is to provide a patch support in which strong adhesion between the two main surfaces is prevented, thereby enabling the efficient manufacture of patches. [Solution] The adhesive patch support according to the present invention comprises a film laminate formed by laminating a first film layer containing a polyester resin and a second film layer containing a resin with a lower glass transition temperature than the polyester resin. In addition, the main surface of the second film layer exposed in the adhesive patch support is characterized by having an uneven structure. This configuration prevents the two main surfaces of the adhesive patch support according to the present invention from adhering strongly to each other.
