PROBLEM TO BE SOLVED: To provide an imaging apparatus having an FPC capable of reducing a mismatch in characteristic impedance of a signal wiring without employing a multilayer substrate as the FPC.SOLUTION: An imaging apparatus comprises an imaging apparatus body, a shaft disposed in the imaging apparatus body, and an FPC held having a part thereof wound around the shaft, and the FPC is constituted on one side, and includes at least one set of differential wirings and a first GND wiring arranged on both sides of the differential wirings, an expansion shape of the part wound around the shaft being a substantially channel shape. At the part wound around the shaft, the first GND wiring or a second GND wiring different from the first GND wiring is arranged at FPCs of upper and lower layers at a part overlapping with a part where a wiring direction of the differential wirings in a region where the FPCs overlap with each other is parallel to the shaft.SELECTED DRAWING: Figure 5(a) |
