の厚みは、２Ｏｆｆで、一定とした。a. A hot melt adhesive 13 was coated on the adhering surface of a fluororesin film 11 having a thickness of 25 mm using a screen printer. As shown in FIG. 3, the coating pattern consists of a lattice-like coated portion 21 and the remaining non-coated portions 22. in this case,
For comparison, as shown in Table 1, the coating portion 21
The pitch P of the grating is constant, and the width W of the grating is changed.
We have prepared various samples. In addition, the coating part 21
The thickness was kept constant at 2Off.
