An imaging module includes an electrical cable； an imaging device； and a flexible wiring board with wirings electrically connecting the imaging device with the electrical cable, in which the flexible wiring board has a device mounting portion mounting the imaging device, and a rear portion bending at a bent portion formed in only one end portion of both end portions of the device mounting portion in a longitudinal direction thereof, and extending to an opposite to the imaging device, in which the device mounting portion has a mounting surface which is a surface intersecting an axial direction of a distal end of the electrical cable, and on which the imaging device is mounted, and in which the wirings extend from the mounting surface and pass through the bent portion, and then the wirings and the electrical cable are connected together at the rear portion.
