According to one embodiment, an electronic device includes an electronic component and a circuit board. The electronic component includes a metal material. The circuit board includes a first surface on which the electronic component is mounted and a second surface opposite the first surface. The electronic component includes a contact surface configured to be in contact with the first surface, and is configured to have the center of gravity at a location displaced from the center of the contact surface. The electronic component is temporarily fixed by a magnetic force that attracts the metal material from the second surface with the contact surface being in contact with the first surface.
