Abstract: A multilayer wiring board includes a core insulating layer with a first conductive wiring, a first insulating layer with a softening temperature lower than the core insulating layer, and a second insulating layer formed on the core insulating layer through the first insulating layer, the second insulating layer with a second conductive wiring electrically connected to the first conductive wiring and a softening temperature higher than the first insulating layer. The first insulating layer is mainly formed of a liquid crystal polymer. The core insulating layer and the second insulating layer are mainly formed of a polyimide resin or a bismaleimide triazine resin. The first conductive wiring and the second conductive wiring are electrically connected through a conductive via formed penetrating through the first insulating layer and the second insulating layer in a thickness direction.
