Abstract
A coil device may be capable of varying the gap of a coil so that several devices may be wirelessly charged simultaneously or a single device may be wirelessly charged with concentrated power. The coil device may include: a case having a reception space and varying a charging area upon a user's selection; and a coil part, having, in the reception space of the case, a coil body formed of a wound conductor having a predetermined length. A gap of the wound conductor of the coil body varies as the charging area of the case varies.
