Abstract
An FPC is constructed of two FPC branches, and a connection line that connects to a controller. Printed wiring of the connection line includes ten printed wires. The central four printed wires are signal reception wires, which are connected to two converters (sensors). Grounding wires are provided on both sides of the four signal reception wires. Two outer signal wires are provided adjacent to the grounding wires, respectively toward the outsides thereof. Further, two more grounding wires are provided adjacent to the outer signal wires, respectively on the outsides thereof. This construction results in shielding of all of the signal wires. This relationship is maintained in the FPC branches as well.
