FIG. 1 is an enlarged explanatory view of a hot melt adhesive transfer sheet used in an embodiment of the present invention, wherein 1 is a base film such as a 75 μm thick polyester film, and both sides of the base film 1 are separated by a silicon coating or the like. Mold processing layers 2A and 2B are formed. On one surface of the base film 1, a 30 μm-thick hot melt adhesive layer 3 such as glycol phthalate is provided via a release treatment layer 2A.
Here, the release treatment layer 2A interposed between the base film 1 and the hot melt adhesive layer 3 is the hot melt adhesive layer 3A.
Is intended to be peelable from the base film 1 and to provide an appropriate adhesive force so as not to peel off too much. Further, as shown in FIG. 2, the release treatment layer 2B on the back side of the base film 1 is made of the hot melt adhesive transfer sheet shown in the embodiment.
This is formed so that the hot melt adhesive layer 3 does not move to the back side of the base film when the roll 10 is wound around the reel 11 and stored.

なお、ホットメルト接着剤層3の厚みは用途に応じて
5μ乃至200μの範囲で適当に設定できる。
The thickness of the hot melt adhesive layer 3 can be appropriately set in the range of 5 μm to 200 μm depending on the application.

但し、ホットメルト接着剤層3の厚みが5μ未満では
厚み不足であり、200μを越えると厚みが過大となって
転写の押圧力で厚みが変動してしまう危険性があるので
好ましくない。
However, if the thickness of the hot melt adhesive layer 3 is less than 5 μm, the thickness is insufficient, and if it exceeds 200 μm, the thickness becomes excessively large and the thickness may fluctuate due to the pressing force of the transfer.
