Abstract

Provided are an electric device and a heat radiator capable of suppressing vibration caused by external stress of the heat radiator. The electric device includes a substrate; an electronic component attached to the substrate; and a heat radiator including at least one first fin, and a second fin facing the first fin, thermally connected to the first fin, and provided at a position closer to an attachment surface of the substrate than any of the first fins. The heat radiator is thermally connected to the electronic component, and one end of an attachment member is attached to the first fin, and another end of the attachment member is attached to the substrate. The attachment member has a height with respect to the attachment surface that is higher than a thickness of the first fin.
