An electromagnetic coupling device electromagnetically connects a door handle side circuit of a door handle with a door main body side circuit of a door main body. This electromagnetic coupling device includes a door handle side coupling unit, a door main body side coupling unit, a door handle side coupling unit, a handle side support unit that supports the door handle, and a connector body that supports the door main body side coupling unit in a vehicle door main body. The door handle side coupling unit is electromagnetically coupled with the door main body side coupling unit without making contact therewith. At least one of the handle side support unit and the connector body restricts the relative movement, caused by rotation of the door handle, of the door handle side coupling unit and the door main body side coupling unit.
