Abstract
A multilayer circuit board includes a board body including insulator layers stacked upon each other, a first land pattern at the board body to mount a passive component, a second land pattern at the board body to mount an active component, and a heat-dissipation layer between the insulator layers and extending along main surfaces of the insulator layers. The heat-dissipation layer includes a hole extending therethrough in a stacking direction of the insulator layers. In a plan view from the stacking direction, an outer edge of the hole of the heat-dissipation layer is on an outer side of the first land pattern, or overlaps the first land pattern.
