PROBLEM TO BE SOLVED: To provide an endoscope capable of detecting breakage of a treatment instrument insertion passage, an endoscope apparatus provided with this endoscope, a damage detection method of a treatment instrument insertion passage, and a program. An endoscope (1) is integrally formed with a treatment instrument insertion passage (14) formed of a flexible tubular member, and is arranged in a circumferential direction and a longitudinal direction of the treatment instrument insertion passage (14). It is provided with a linear conductive member 17 arranged across and a damage detection unit 26A that detects a conductive state of the conductive member 17 and detects damage to the treatment instrument insertion passage 14.
