Electrical device

An electrical device in which a component including a ferrite core is fixed, comprising:

• a circuit board;
• a cable passing through the ferrite core of the component, said cable including one end portion, said one end portion being electrically connected to the circuit board;
• a fixing device to which the ferrite core is fixed;
• and
• a fixing portion for fixing the fixing device,
• wherein said fixing device includes a holding portion for holding the ferrite core and a fixed portion fixed to the fixing portion, and
• said holding portion includes a hook claw disposed at a distal end portion thereof, a hole portion for receiving a base portion of the hook claw and engaging with the distal end portion, an attaching portion for attaching the ferrite core, a first movement restriction member for restricting a movement of the ferrite core in a direction that the cable extends, and a second movement restriction member for restricting a movement of the ferrite core in a direction perpendicular to the direction that the cable extends.
