PROBLEM TO BE SOLVED: To dissolve the parting and bypassing of a feedback current route even when a wiring pattern is made high in density and complicated.;SOLUTION: In the case that a part Pw of the wiring pattern Pa1 of a wiring layer L2 is overlapped with a non-conductive part between the respective conductive part patterns Pb1 and Pb2 of a plane layer L2 and the feedback current route of the plane layer L1 is parted, the conductive bridge 21 of the wiring layer L2 connected to the respective conductive part patterns Pb1 and Pb2 of the plane layer L1 through respective through-holes 23 on both sides of the part Pw over the part Pw along the wiring pattern Pa1 at the part Pw is designed.;COPYRIGHT: (C)2005,JPO&NCIPI
