An electronic device includes a heat sink, where heat dissipating gel is interposed between the heat sink and a side of an electronic component, which is mounted on a substrate, opposite from the substrate. The electronic component includes an electrical conductor electrically connected to a chip, and an insulator portion that molds the chip with the electrical conductor. The heat sink includes a non-abutting surface that faces the electrical conductor of the electronic component, the heat dissipating gel interposed between the non-abutting surface and the electrical conductor, and an abutting surface that is positioned closer toward the substrate than the non-abutting surface is and abuttable with the insulator portion. Accordingly, when the abutting surface of the heat sink abuts the insulator portion of the electronic component, the non-abutting surface of the heat sink is prevented from abutting the electrical conductor of the electronic component.
