Abstract:
A process for the production of an inductor device, comprising the steps of:forming a green sheet to form an insulating layer; forming a plurality of conductive coil pattern units on the surface of the green sheet so that a plurality of unit sections each including a single coil pattern unit are arranged on the surface of the green sheet and each two coil pattern units adjoining in a substantially perpendicular direction to a longitudinal direction of the unit sections are arranged centro-symmetrically with respect to a center point of a vertical boundary line of adjoining unit sections; stacking a plurality of green sheets formed with the plurality of coil pattern units arranged centro-symmetrically so that the coil pattern units are alternately stacked and connecting the upper and lower coil pattern units separated by the green sheets to form a coil shape; and sintering the stacked green sheets.
