Beschreibung
Zusammenfassung:	An electronic device including a substrate, a first electronic component provided on the substrate, a second electronic component provided on the substrate and having a thickness in a normal direction of the substrate smaller than that of the first electronic component, a first heat conductive member in contact with the first electronic component, a second heat conductive member in contact with the second electronic component, and a heat sink attached to the substrate, in which the heat sink includes a base portion provided so as to cover the first electronic component and the second electronic component and attached to the substrate, a first protruding portion that protrudes from the base portion toward the first electronic component and is in contact with the first heat conductive member, and a second protruding portion that protrudes from the base portion toward the second electronic component and is in contact with the second heat conductive member, and a length of the first protruding portion in the normal direction is shorter than a length of the second protruding portion in the normal direction.
