    Abstract: A wiring board includes an insulating layer, first and second pads provided on the insulating layer and including a first surface in contact with the insulating layer, a second surface opposite to the first surface, and a side surface connecting the first and second surfaces, respectively, and a protective insulating layer provided above the insulating layer. The first and second pads have a portion exposed inside an opening in the protective insulating layer. The first pad has a portion opposing the second pad without the protective insulating layer interposed between the first and second pads. A region of the second surface of the first and second pads exposed from the protective insulating layer is covered with a plating layer. A region of the side surface of the first and second pads exposed from the protective insulating layer is exposed from the plating layer.

    Abstract: A wiring board according to the present disclosure has at least a structure in which a wiring conductor layer is layered on a surface of an insulating layer containing particles of silica, and some particles of silica among the particles of silica contained in the insulating layer are partially exposed on the surface of the insulating layer. The wiring conductor layer includes a seed layer in contact with the insulating layer and a plated conductor layer formed on a surface of the seed layer. At a contact surface between the exposed portions of the particles of silica and the seed layer, an amorphous layer of silica derived from the particles of silica and an amorphous layer of metal derived from metal forming the seed layer are present.
