A wiring board and an electronic package maintain the flatness of the surface of the wiring board. The wiring board includes a flat insulating layer having a flat upper surface, and a conductive layer on the upper surface of the insulating layer with a space left from an outer edge of the insulating layer. The conductive layer includes a peripheral portion, a central portion inward from the peripheral portion, and a linear portion included in the central portion. The peripheral portion is raised along the outer edge of the insulating layer. The linear portion is raised to a height position of the peripheral portion.
