ABSTRACT:
An inductance device which has a structure wherein insulating layers and coil conductors are alternately laminated and the coil conductors are electrically connected with one another. For example, insulating sheets each of which has a coil conductor thereon and insulating sheets each of which has a guard electrode thereon are alternately laminated. In the laminate state, the coil conductors are serially connected by through holes made in the insulating sheets, and thus a coil is formed. There is provided a guard electrode between two adjacent coil conductors, and the guard electrode electrically shields the coil conductors from each other.
