`adhesive layer 30 and the second adhesive layer 50 are made
`of acrylic resin. The thickness of the first adhesive
`layer 30
`and the second adhesive layer 50 are about 30 pm.
`[0017] Referring to FIG. 2, an embodiment of a method for
`the adhesive double-sided tape is disclosed as
`manufacturing
`follows.
`In step S201, a base board 10 is provided.
`[001S]
`In the
`the base board 10 is made of PET,
`embodiment,

`In step S202, a roller is provided,
`through holes 12 is defined in the base board 10 by rolling the
`In the illustrated
`roller
`thereon.
`the through
`embodiment,
`holes 12 are circular holes having a diameter of about
`I pm.
`The distances between adjacent
`through holes are substan-
`tially equal and are about 10 pm.
`In step S203, the first adhesive layer 30 is formed on
`[0020]
`one surface of the base board 10 by transfer printing.
`In the
`the first adhesive layer 30 is made of
`illustrated embodiment,
`acrylic resin, and the thickness ofthe first adhesive layer 30 is
`about 10 pm.
`In step S204, the second adhesive layer 50 is formed
`[0021]
`on the other surface of the base board 10 by transfer printing.
