    摘要: A method of manufacturing a multilayer wiring board includes a stacking process in which insulating layers, each of which includes a ceramic layer and a shrinkage suppression layer being stacked on top of the ceramic layer, are stacked on top of one another, a press-bonding process in which the insulating layers are press-bonded, so that a multilayer body is formed, and a firing process in which the multilayer body is fired. In the stacking process, in each of the insulating layers, a wiring electrode is formed on a surface of the shrinkage suppression layer on the opposite side to the surface of the layer facing the ceramic layer, and the thickness of a peripheral area of the shrinkage suppression layer located around the area of the shrinkage suppression layer that is in contact with the electrode is larger than those of portions of the layer except for the peripheral area.
