Title: ELECTRONIC DEVICE
Abstract:
An electronic component (20) is provided close to one surface (101) of a heat sink (10), and generates heat during operation. A heat conducting member (40) is provided between the heat sink (10) and the electronic component (20), and is capable of conducting heat from the electronic component (20) to the heat sink (10). A joining member (50) is provided so as to join at least one part of the electronic component (20) outer edge in the circumferential direction, and the heat sink (10). Also, the joining member (50) has a linear expansion coefficient that is smaller than the linear expansion coefficient of the heat conducting member (40).
