Abstract: In a method for manufacturing a multilayer substrate, conductive patterns to define mounting electrodes are formed on a principal surface of a first base layer, and conductive patterns are formed on principal surfaces of other base layers. The base layers are stacked such that the principal surface of the first base layer is the outermost surface. The stacked base layers are laminated by pressing an elastic body to the side of the first base layer to form a multilayer body. In the multilayer body, the conductive patterns are arranged such that the proportion of the conductive patterns in regions overlapping the conductive patterns on the first base layer as viewed in the stacking direction is lower than that in a region surrounding the regions overlapping the conductive patterns.
