Abstract
A multilayer substrate includes a multilayer body including resin layers stacked in a Z-axis direction, a signal conductor layer, and one or more through conductors passing through a first resin layer in the Z-axis direction. A first main surface of the first resin layer includes one or more hollow portions not in contact with the signal conductor layer and overlapping the signal conductor layer when viewed in the Z-axis direction. Each of the one or more hollow portions and the one or more through conductors includes a tapered region in which each of a cross-sectional area of the one or more hollow portions orthogonal to the Z-axis direction and a cross-sectional area of the one or more through conductors orthogonal to the Z-axis direction increases toward the first main surface. The tapered region is in contact with the first main surface of the first resin layer.
