PROBLEM TO BE SOLVED: To provide a wiring board which allows for effective suppression of problems, i.e., floating or peeling of wiring from an insulating layer, in a wiring board where one or more conductor layers and insulating layers are laminated.SOLUTION: In a wiring board where one or more conductor layers and insulating layers are laminated, the conductor layer includes first wiring formed on the insulating layer, at the ends of an abutment surface against the insulating layer and a surface facing the insulating layer, and having a spaced surface not abutting against the insulating layer, and second wiring filling between the insulating layer and spaced surface, and electrically connecting the first wiring. |
