PURPOSE:To make an air cross-over part of an upper layer winding mechanically firm and reduce a capacity between the wirings by forming the air cross- over part into a shape of a corrugated plate. CONSTITUTION:An upper layer winding 5 is formed over linear patterns 4. An air bridge of the wiring 5 is formed into a shape of a corrugated plate so that the bending strength of the longitudinal direction of the wiring 5 is improved. With this method, the air cross-over part is mechanically strengthened and a capacity between the wirings is reduced. |
