Abstract

PURPOSE:To eliminate the need for positioning by reducing the number of patterning to one by removing a substrate after covering the top surface of a coil pattern formed on one side of the substrate. CONSTITUTION:On conductive (copper) coating 2 of substrate 1, photo resist layer 3 is formed in a spiral pattern shape. On coating 2 of copper, sticking layer 4 of copper is formed next. Then, resin layer 5 is applied. Substrate 1 and copper coating 2 are both removed here. Then, sticking layer 6 of copper is formed on flank 4a of sticking layer 4 of copper. Next, resin layer 7 is formed, so that the coil will be completed. This manufacturing method requires only single patterning and no positioning.
