PROBLEM TO BE SOLVED: To provide an endoscope of simple constitution, capable of improving substrate assembling work efficiency, and preventing wire breakage/damage. SOLUTION: A switching circuit part 26 to be included in a tip hard part 20 is composed of a flexible substrate 261 comprising substrate parts 26a bendably connected through bending parts 26b having flexibility. A regulation part 26c to prevent over-bending is provided on the substrate part 26a of the flexible substrate 26a to be bendable through a connection part 26d having flexibility. As the substrate parts 26a are bent to be overlapped through the bending parts 26b, the regulation parts 26c are bent at the connection parts 26d to be applied to a substrate surface of the substrate part 26a facing it, thereby the substrate part 26a is prevented from being further bent.
