An endoscope includes a drive force transmitting section attached to an insertion main body, and configured to transmit rotational drive force that rotates an attachment unit to the attachment unit, and a member inserting portion provided to a proximal direction side of an insertion section. The endoscope includes a first linear member insertable into the insertion section from the member inserting portion and removable from the insertion section through the member inserting portion, and has a distal end connectable to the drive force transmitting section while being inserted into the insertion section. The first linear member is configured to transmit the rotational drive force to the drive force transmitting section when rotated while being connected to the drive force transmitting section.
