ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/057421
Kind Code:
A1
Abstract:
This electronic device (101) is provided with: a case (1); a coil antenna (10) that is contained within the case (1) and has a winding axis (AX1) and coil open ends (E1, E2); and conductive members (21, 22) that are contained within the case (1). The conductive members (21, 22) have a first surface (S1) that is parallel to the winding axis (AX1) and is positioned adjacent to the coil antenna (10). At least one of the coil open ends (E1, E2) overlaps the conductive members (21, 22) when viewed from the direction (X direction) perpendicular to the first surface (S1). When viewed from the X direction, the length (Z2) of the conductive members (21, 22) in the direction (Z direction) perpendicular to the winding axis (AX1) of the coil antenna (10) is longer than the length (Z1) of the coil antenna (10) in the Z direction (Z2 > Z1), and the length (Y2) of the conductive members (21, 22) in the winding axis (AX1) direction (Y direction) is equal to or longer than the length (Y1) of the coil antenna (10) in the Y direction (Y2 ≥ Y1).
