Abstract: A radio-frequency module includes a mounting board, a first electronic component, and a second electronic component. The second electronic component is lower in height than the first electronic component. The mounting board includes dielectric layers, conductive layers, and via-conductors. In the mounting board, the dielectric layers and the conductive layers are stacked in the thickness direction of the mounting board. The mounting board has a first region and a second region. The first region overlaps the first electronic component and extends from a first major surface to a second major surface. The second region overlaps the second electronic component and extends from the first major surface to the second major surface. In the mounting board, the conductive layers in the first region are fewer than the conductive layers in the second region. In the mounting board, the first region is thinner than the second region.
