ことにより形成される。 The terminal part 4 is made by punching out the base material 1 with the adhesive layer 2 formed on one side using female and male punching dies with an adjusted gap, so that the punched part of the base material 1 has a warp larger than the thickness of the adhesive layer 2. It is formed by pressing the whole thing and bending the warp to the surface of the adhesive layer and inverting it.

Direct contact provides a reliable energizing effect. Furthermore, because the terminal ends of the base material 1 are formed into a thin layer due to the ductility of the metal foil and cover the surface of the pressure-sensitive adhesive layer, the height of the terminal portion is the same as or slightly higher than the surface of the adhesive layer. Only.
