    Abstract: A core device includes: a core having a mounting surface; a first conductor including a first body portion extending along the mounting surface inside the core; and a second conductor including a second body portion that extends along the mounting surface inside the core and faces the first body portion. The first body portion has a first side surface having a first thickness in a direction perpendicular to the mounting surface and a first main surface having a first width in a direction parallel to the mounting surface. The second body portion has a second side surface having a second thickness in the direction perpendicular to the mounting surface and a second main surface having a second width in the direction parallel to the mounting surface. The second width is narrower than the first width when the first body portion and the second body portion face each other.

    Abstract: A coil device comprises a core and a coil including a folded metal plate member having a pair of main surfaces extending in a direction perpendicular to a bottom surface of the core. The coil includes a first conductor, a second conductor, and a third conductor. The first conductor includes a first main portion, which is disposed inside the core, and a first terminal portion, which is connected to the first main portion and partly protrudes below the bottom surface. The second conductor includes a second main portion, which is disposed inside the core and farther from the bottom surface than the first main portion, and a second terminal portion, which is connected to the second main portion and partly protrudes below the bottom surface. The third conductor includes a joint portion connecting the first conductor and the second conductor and a locating portion partly protruding below the bottom surface.

    Abstract: To provide a coil device capable of preventing a short-circuit failure during mounting. A coil device 1 includes a core having a mounting surface, a first conductor formed of a wire, and a second conductor formed of a conductor plate. The first conductor includes a first body portion extending along the mounting surface inside the core. The second conductor includes a second body portion extending along the mounting surface inside the core and facing the first body portion. In a direction in which the first body portion and the second body portion face each other, the first body portion is positioned on one side of the core, and the first body portion and the second body portion are offset to the one side of the core on which the first body portion is positioned.
