Claim:
1. A resonant coupler that wirelessly transmits a signal between a first resonant line and a second resonant line, the resonant coupler comprising: a first substrate; and a second substrate across from the first substrate, wherein the first substrate includes, on a main surface: when viewed in a direction perpendicular to the main surface of the first substrate, the first substrate further includes, on the main surface, a first ground line peripheral to the first resonant line, the first grounding part is a line that grounds the first end of the first resonant line by connecting the first end of the first resonant line to the first ground line, the second substrate further includes, on the main surface, a second ground line peripheral to the second resonant line, and the second grounding part is a line that grounds the first end of the second resonant line by connecting the first end of the second resonant line to the second ground line.
