Kind Code:
A1
Abstract:
The present invention is provided with: a ground conductor pattern (11) constituted by conductors spread in a planar shape; a notch (12) formed in the ground conductor pattern (11) and connected to the outer edge of the ground conductor pattern (11); a coil conductor pattern (21) having a coil aperture (CA) that overlaps the notch (12) in plan view of the ground conductor pattern (11); and a bezel (31) which faces the outer edge of the ground conductor pattern (11) connected to the notch (12) in a plan view. When viewed in the direction along the surface of the ground conductor pattern (11), the coil conductor pattern (21) and the ground conductor pattern (11) are in different positions in the normal direction, and at least a part of the bezel (31) is positioned on the opposite side in relation to the ground conductor pattern (11) in the normal direction in relation to the surface of the ground conductor pattern (11).
