The disclosure provides an electronic apparatus. The electronic apparatus includes a substrate, a first metal layer, an insulating layer, a first conductor, an electronic assembly and a transistor circuit die. The first metal layer is disposed on the substrate. The insulating layer is disposed on the substrate. The first conductor is formed in a first via of the insulating layer. The electronic assembly is disposed on the substrate and electrically connected to the first metal layer through the first conductor. The transistor circuit die is electrically connected to the first metal layer.
