An endoscope includes an image pickup module having an optical axis that defines a visual field direction and provided with an electric contact, a cable that is disposed on a proximal end side of the image pickup module and transfers an image pickup signal generated by the image pickup module, a channel provided beside the image pickup module, and a movable board electrically connecting the electric contact and the cable to transfer the image pickup signal and including a movable portion capable of forming a curved surface that is freely displaceable in an optical axis direction. The movable portion of the movable board is arranged at a position where a distance between the curved surface and the channel is longer than a distance between the curved surface and the optical axis.
