An inductor device including a device body having a plurality of insulating layers; a plurality of conductive coil pattern units formed inside the device body between insulating layers along a single planar direction, coil pattern units adjoining each other in the single plane being centro-symmetric patterns with respect to a center point of a boundary line between unit sections containing coil pattern units; and connection portions connecting upper and lower coil pattern units separated by the insulating layers to form a coil. It is possible to obtain an inductor device able to suppress the stack deviation without complicating the production process even if the device is made small in size.
