Abstract
A wiring board includes a base layer, a plurality of connection terminals and a surface layer. The base layer is electrically insulative. The plurality of connection terminals are conductive and formed on the base layer. The surface layer is electrically insulative, and fills gaps between the plurality of connection terminals on the base layer. The connection terminals include a base portion made of a conductive first metal and a coating portion made of a conductive second metal that is different from the first metal. The coating portion penetrates the surface layer, and coats the base portion to the base layer.
