A multilayered wiring board comprising a first stacked structure consisting essentially of a first insulating layer having a first parallel conductor array and a second insulating layer formed thereon, having a second parallel conductor array oriented orthogonal to the first parallel conductor array, the first and second parallel conductor arrays being electrically interconnected by a first through conductor array; and a second stacked structure consisting essentially of a third insulating layer having a third parallel conductor array crossing at an angle of 30 to 60 degrees to the first parallel conductor array and a fourth insulating layer formed on top of the third insulating layer, having a fourth parallel conductor array orthogonal to the third parallel conductor array, the third and fourth parallel conductor arrays being electrically interconnected by a second through conductor array, wherein the second stacked structure is overlaid on the first stacked structure by interposing therebetween an intermediate insulating layer having a conductive layer, and the first or second parallel conductor array and the third or fourth parallel conductor array are electrically interconnected by a third through conductor array.
