PURPOSE:To improve passage property and to improve the transition property of conductor material to a substance to be printed by forming a spare opening of dimensions larger than the required dimensions of an opening for conductor pattern along the required conductor pattern, and covering the inside of the space opening and forming the opening for conductor pattern of required dimensions. CONSTITUTION:At a base material 4, a spare opening 10 of dimensions C larger than the required dimension B of an opening 6 for conductor pattern is formed along a conductor pattern P by photoetching. The base material 4 is covered (plated) all over with a cover material 8 of D in thickness. When covering the base material 4 with the cover material 8, the inner face 10a of the spare opening 10 is also covered in the same thickness D with the cover material 8, and an opening 6 for conductor pattern is formed, and also by the thickness D of the cover material this opening 6 for conductor pattern is formed in required dimensions B. Accordingly, the inner face 6a of the opening 6 for conductor pattern is formed smoothly by the cover material 8a on the inner face. |
