Abstract
An objective is to achieve an endoscope in which a distal part of an insertion unit has a reduced diameter, yet the endoscope has good pushability so that buckling at the distal part can be avoided. This endoscope is provided with: an imaging unit having a lens and an imaging element; a resin tube which extends from the imaging unit to the proximal side opposite the distal side, and through which a cable conductively connected to the imaging element is inserted; and an elastic wire which has a distal end disposed outwardly of the imaging element, is inserted in and extends through the resin tube, and has flexibility and bending stiffness.
