ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/008573
Kind Code:
A1
Abstract:
An electronic device (301) is provided with: a first circuit (circuit board (71)); a second circuit (circuit configured on a mounting board (201)); and an inductor bridge (101A) connecting the first circuit and the second circuit. The inductor bridge (101A) includes an insulating base material (10), and a conical coil (3) formed in the insulating base material (10). The conical coil (3) includes a plurality of looped conductors (a small-diameter looped conductor (32) and a large-diameter looped conductor (31)) arranged along a winding axis direction (Z-axis direction). The plurality of looped conductors have inner and outer diameters which vary in one direction along the Z-axis direction. Of the plurality of looped conductors, the large-diameter looped conductor (31) with the largest inner and outer diameters is disposed in a position such that, when the inductor bridge (101A) is bent, the inner and outer diameters expand along the insulating base material (10) to a greater degree than the other looped conductor (small-diameter looped conductor (32)).
