膜の密着性が弱くなるためである。[0004] In order to prevent the bleeding of the parting line when the masking parting tape is attached to the parting line of the V-shaped groove, the masking parting tape is pressure-bonded by rubbing with a finger on the masking parting tape. At this time, not only on the masking parting tape but also on the plasma-treated surface of the periphery B, the plasma treatment effect is weakened and the adhesion of the top coat film is weakened.
