    摘要: A multilayer wiring substrate includes a laminate structure in which resin insulation layers and conductor layers are alternately laminated. The resin insulation layers include first-type resin insulation layers, and second-type resin insulation layers, each of which contains an inorganic material in a larger amount and is smaller in thermal expansion coefficient as compared with first-type resin insulation layers. On a cross section of the laminate structure taken along a thickness direction thereof, the ratio of a total thickness of the second-type resin insulation layers located in an area A2 to a thickness corresponding to the area A2 is greater than the ratio of a total thickness of the second-type resin insulation layers located in an area A1 to a thickness corresponding to the area A1. The laminate structure is warped such that the laminate structure is convex toward the side where the second main face is present.
