Abstract
A wiring board has vias which penetrate the wiring board from one side to the other side. The vias are radially arranged in the direction from one side to the other side so that the interval between the vias on one side can be made smaller than the interval between the vias on the other side. In order to prevent the vias from being electrically short-circuited to each other, even if the interval between the vias provided on one side of the wiring board is extremely reduced, a plurality of vias are radially arranged in the direction from one side of the wiring board to the other side so that an interval between the vias on one side of the wiring board can be made smaller than interval of the vias on the other side. A conductor forming the core portion of the via is coated with a sheath portion made of insulating material.
