Abstract: Embodiments of the present invention provide a wiring substrate which is excellent in terms of the reliability of connection between the wiring substrate and a semiconductor chip. In some embodiments the wiring substrate comprises a first build-up layer in which resin insulation layers and conductor layers are laminated alternately. The outermost conductor layer can include a plurality of connection terminal portions to which a semiconductor chip is flip-chip connected. The plurality of connection terminal portions can be exposed through openings of a solder resist layer. Each of the connection terminal portions includes a connection region to which a connection terminal of the semiconductor chip is to be connected, and a wiring region which extends in a planar direction from the connection region and which is narrower than the connection region. The surface of the wiring region has a solder wettability lower than that of the surface of the connection region.
