Magnetic device

A magnetic device, comprising:

• a first element section including a first magnetic layer, a second magnetic layer, and a first nonmagnetic layer provided between the first magnetic layer and the second magnetic layer in a first direction from the first magnetic layer to the second magnetic layer;
• a first conductive member, the first conductive member including a first conductive portion, a second conductive portion, and a third conductive portion, a second direction from the first conductive portion to the second conductive portion crossing the first direction, the third conductive portion being provided between the first conductive portion and the second conductive portion in the second direction, the first magnetic layer being provided between the third conductive portion and the second magnetic layer in the first direction;
• and
• a first insulating member including a first insulating portion, the third conductive portion being is provided between a part of the first insulating portion and the first element section in the first direction, the third conductive portion being provided between the first insulating portion and the first magnetic layer in the first direction, a first insulating portion width of the first insulating portion along a third direction being narrower than a first conductive member width of the first conductive member along the third direction, the third direction crossing a plane including the first direction and the second direction.
