The invention relates to a method for producing an endoscope insertion tube (2). The insertion tube (2) has a proximal passive flexible section (20) and a distal bending section (A). The passive flexible section (20) and the bending section (A) are integral. Individual sections (201, 202) are provided in the flexible section (20) provided as a tube-type element such that adjacent individual sections (201, 202) are at equal distances from each other.
