The endoscope includes an insertion unit having a first area in which an attenuation rate of a repulsive force generated when bent is a positive value of 30% or lower. More preferably, the attenuation rate of the first area is 10% or higher and 30% or lower. The first area is in a range of 200 mm to 800 mm from a distal end side of the insertion unit.
