    摘要: A circuit board is disclosed that includes a plurality of circuit board layers located one on top of the other. The plurality of circuit board layers includes a topmost circuit board layer and a bottommost circuit board layer, wherein the topmost circuit board layer forms a top of the circuit board, wherein the bottommost circuit board layer forms a bottom of the circuit board, and wherein the plurality of circuit board layers together forms an end circuit-board edge that runs perpendicularly to the top and the bottom of the circuit board. The end circuit-board edge is provided with a coating made of an insulating material.

    摘要: The wiring board according to the present disclosure includes: a first insulating layer including insulating particles; a plurality of first conductors located on the first insulating layer at an interval of a first distance from each other; a second conductor located on the first insulating layer at an interval of a second distance from the first conductor; and a second insulating layer located on the first insulating layer to cover the first conductor and the second conductors and including the insulating particles. When a boundary portion between the first insulating layer and the second insulating layer is viewed in cross-section in the thickness direction, the ratio of a first area occupied by the insulating particles in a first boundary portion including the first distance is higher than the ratio of a second area occupied by the insulating particles in a second boundary portion including the second distance.
