Abstract
An electronic device has a substrate, a heat sink, and a heat conductive material. The substrate has a first surface on which an electronic part is arranged. The heat sink has (i) a second surface facing the first surface and distanced from the electronic part and (ii) an annular groove extending annularly and defining an area that is circled by the annular groove on the second surface and faces the electronic part. The heat conductive material is arranged between the first surface and the second surface to be in contact with the electronic part and the annular groove. The heat conductive material guides heat generated by the electronic part to the heat sink.
