COIL DEVICE

Abstract: a coil device includes a core containing a magnetic material and having a mounting surface and a side surface extending in a direction perpendicular to the mounting surface, and a wire including a winding portion disposed inside the core and a lead-out portion drawn out from the winding portion. the lead-out portion includes a proximal portion continuing to the winding portion and a flattened portion continuing to the proximal portion and being squeezed flat. the flattened portion includes an embedded portion disposed inside the core and a terminal portion having a plating layer and being disposed outside the core. the embedded portion extends diagonally from the proximal portion to the side surface. the terminal portion is exposed from the core at a central portion of the side surface in the direction perpendicular to the mounting surface. the terminal portion extends from the central portion to the mounting surface.
