ABSTRACT:
Provided is an electronic device that includes an LTCC inductor including a first sheet disposed on a substrate and including a first conductive pattern, a second sheet disposed on the first sheet and including a second conductive pattern, and a via electrically connecting the first conductive pattern to the second conductive pattern, and a spacer disposed on a lower surface of the first sheet to provide an air gap between the substrate and the first sheet, wherein the first conductive pattern is exposed out of the lower surface of the first sheet.
