Claim of US Patent No. 10,798,820

1. A connector-equipped circuit body comprising:a circuit body configured by a flexible board where a wiring pattern formed of a conductor for electric connection is provided; and
a connector connected to the circuit body,
wherein at a connection portion of electrical connection between the circuit body and the connector, an auxiliary conductive layer independent of the wiring pattern is provided so as to be multilayered for the wiring pattern,
wherein the circuit body includes an upper side metal layer, and a lower side metal layer which is laminated to sandwich a resin layer between the upper side metal layer and the lower side metal layer,
wherein the upper side metal layer has a plurality of upper side wiring patterns connected to the connector, the plurality of upper side wiring patterns being provided, as the wiring pattern, to be independent of each other in the upper side metal layer,
wherein the lower side metal layer has a plurality of lower side wiring patterns connected to at least a part of the plurality of upper side wiring patterns via a hole, the plurality of lower side metal layer being provided, as the wiring pattern, in the lower side metal layer without a connection to the connector, and
wherein the auxiliary conductive layer is provided in the lower side metal layer.
