<p>This electronic device contains a heat-dissipating member and a magnetic member placed on said heat-dissipating member. The magnetic member comprises a magnetic core, said magnetic core comprising a first core that contacts the heat-dissipating member and a second core located on the side of the first core that faces away from the heat-dissipating member, and a coil wound around said magnetic core. The heat-dissipating member has an accommodating recess that accommodates at least the first core. Said accommodating recess has a bottom wall, a circumferential wall perpendicular to said bottom wall, and an arc-shaped rounded bottom edge section that connects the bottom wall and the circumferential wall. The first core has the following: a bottom surface positioned so as to face the bottom wall of the accommodating recess; a circumferential surface perpendicular to said bottom surface; and a chamfered section formed at the bottom edge of the first core so as to connect the bottom surface and the circumferential surface. An air gap is provided between said chamfered section and the aforementioned rounded bottom edge section.</p> |
