Classification: CPC H | IPC H

Claim 10:
11. A wireless communication device comprising:
a main substrate;
a wireless communication substrate having an antenna configured to perform wireless communication;
a sub-substrate having a first substrate surface and a second substrate surface opposite to the first substrate surface;
a main connector provided on the main substrate;
a communication connector provided on the wireless communication substrate;
a first connector provided on the sub-substrate and being electrically connected to the main connector such that the sub-substrate is parallel to the main substrate; and
a second connector provided on the sub-substrate and being electrically connected to the communication connector such that the sub-substrate is parallel to the main substrate,
wherein a position of the first connector is a position shifted, in a length direction of the main substrate, from a position of the second connector, seen from a direction orthogonal to the first substrate surface of the sub-substrate;
wherein the first connector is provided on the first substrate surface of the sub-substrate and the second connector is provided on the second substrate surface of the sub-substrate; and
the wireless communication device further comprising a holder covering the sub-substrate and the wireless communication substrate except the first connector and holding the sub-substrate,
wherein the sub-substrate has:
a first area including a first insulating layer, a second insulating layer and a metal layer located between the first insulating layer and the second insulating layer; and
a second area including the first insulating layer, the second insulating layer and a third insulating layer located between the first insulating layer and the second insulating layer, and

wherein the antenna of the wire communication substrate is located such that the antenna overlaps the second area of the sub-substrate and does not overlap the first area of the sub-substrate, seen from the direction orthogonal to the first substrate surface of the sub-substrate.
